That was one of my first thoughts, but came to the conclusion that it couldn't be on measurement grounds, 8' coupled wheelbase (7' on the etch), 6' connecting rods, (7' on the etch) . This is fun, wonder who will actually land this slippery fish? Link to post Share on other sites More sharing options...

RMweb Gold The Johnster Posted September 25, 2020 RMweb Gold Share Posted September 25, 2020 I think the axle holes with springs are for leading wheels in a rigid chassis, not driving wheels, which suggests an early prototype, with inside frames. This makes life even more confusing; I’m not helping, am I mummy? Not wide enough for Pearson 4-2-4T, not broad gauge. Link to post Share on other sites More sharing options...

It does seem to have folk at a loss... Cheers, Mark Mark Any chance of having a photo of the other side please, just to see if there are any fold lines on the rear of the etch Do we recon the folds are on the outside ?

Here's the other side - with no etched fold lines. I'll see if I can find some card & print a copy for folding. Thanks all for taking an interest - it's much appreciated.

It's not from the kit I bought, but I'm puzzled as to what it might be for. There are no coupling rods, but there are some connecting rods that look NER style at first glance. Any ideas please? Cheers, Mark Looking at the center spacer, if both sides are folded down, the front part of the splcer has two folds if the front (wide) part was folded up, as the second part is bent down the wide part fits into the flat part , perhaps for sitting a cylinder on. Between the two big drivers are there cutouts to accept a Bulldog or X03 motor. If the bottom left etch is a front bogie whats the middle etch between the bogie and what we think is a tender coupling. Or is the tender coupling part of the pickups and the holes are to hold the insulator as on the early wills etched chassis ?> Link to post Share on other sites More sharing options...

RMweb Premium John Isherwood Posted September 25, 2020 RMweb Premium Share Posted September 25, 2020 (edited) Being an LNER ignoramus - what is the coupled wheelbase of an LNER G5? Google seems unable to help me with that. John Isherwood. Ignore this - it's clearly something with outside cylinders.

cypherman Posted September 25, 2020 Share Posted September 25, 2020 (edited) Hi all again. Ok to throw something else into the ring. If it is an 0-4-4. Could it be a replacement chassis for a Triang/Hornby M7. But my money is still on an 0-6-2 with a compensated rear driving wheel set. H/D N2 replacement chassis perhaps.

Bucket of Steam Posted September 25, 2020 Share Posted September 25, 2020 I'm sure whoever designed the etch had no idea how many hours of entertainment it would provide decades later. 1 1 3 Link to post Share on other sites More sharing options...
EddieB Posted September 25, 2020 Share Posted September 25, 2020 Pretty sure it's an 0-4-4T given the dummy springs under the driving wheels, the inclined angle of the upper frame for the motor, beneath which are arches for a trailing bogie. Since the other kit was for an NER prototype, it seems reasonable that this is also for an ex-NER loco - a G5? Link to post Share on other sites More sharing options...

hayfield Posted September 25, 2020 Share Posted September 25, 2020 If it were an 0-4-4 t where would the cylinder go ? surely a 4-4-0 loco, but then what about the sub chassis with axle holes and springs 2-6-0 ? or 2-4-0 Link to post Share on other sites More sharing options...
Bucket of Steam Posted September 25, 2020 Share Posted September 25, 2020 (edited) The way that the main chassis has that carefully sculpted thin cross section at the right hand side suggests to me that this is the front of the engine. If that part was intended to fit under a cab, or a bunker, I would expect the top edge to be flat. If we assume ( dangerous ) that the buffers are mounted on the centerline of the right hand end of that thin section, and that the buffers are a normal height above rail level, then can we calculate what diameter driving wheels would be required to hold the buffers at normal height. ( of course it's possible that the buffer centerline is above footplate height, like some Southern engines). A quick visual suggests that would mean very small diameter driving wheels, so probably not a sensible idea.

£1.38 Posted September 26, 2020 Share Posted September 26, 2020 I would concur that the driving wheels must be small. Here's a quick sketch showing how 7ft and 5ft 3in wheels compare for the drivers (4mm scale) - bogie wheels are drawn at 3ft 6in. Even allowing for large flanges, large driving wheels don't look right compared with the etched height of the cutouts for the bogie wheels. Wheelbase is 24mm + 24mm + 27mm, based on the scale in the original photo The diameters I chose were just guesses. If the bogie wheels were slightly bigger and/or set slightly lower then the driving wheels could be a bit bigger - say up to 6ft? 1 Link to post Share on other sites More sharing options...
Bucket of Steam Posted September 26, 2020 Share Posted September 26, 2020 That's a useful view. If you were to draw in a bulldog motor outline fitting into the notches provided for it , it would stick up quite high above rail level, so maybe a largish tank loco or large diameter boiler required to conceal it?

cypherman Posted September 26, 2020 Share Posted September 26, 2020 (edited) Hi all, Well here is a thought. Perhaps it is a generic etch that could be used for both 0-4-4 and 0-6-2. That's why the last set of drivers were on a separate mounting. Did any kit builders ever do this. Make a chassis etch that could be used on several of their different kits. Though looking at what I think is the base fitting for the rear bogie on the botton left it is only big enough to fit a single wheel. My god this is fun and brain taxing........

Bucket of Steam Posted September 26, 2020 Share Posted September 26, 2020 Maybe the etch designer was really bored on day, and thought " I know, I'll put a random selection of chassis parts onto an etch, and then watch the fun when people try to work out what it's for." 1 Link to post Share on other sites More sharing options...

K's and the predecessor who designed the 42/52/72 xx built a 2-8-0T / 2-8-2T admittedly a brass bar chassis but I have 2 etched kits from another manufacturer where you have to solder a frame extension to both sides. I think also there is a Golden Arrow 009 chassis which has 2 alternative driver combinations. Did not Wills Finecast do a southern tank loco either 0-6-0T or 0-4-2T Link to post Share on other sites More sharing options...
Tim V Posted September 26, 2020 Share Posted September 26, 2020 To me that 'extension' looked like a truck. I'm going to bid Adams Radial Tank. 4-4-2, outside cylinders. 1 Link to post Share on other sites More sharing options...

billbedford Posted September 26, 2020 Share Posted September 26, 2020 (edited) It is only 10 mm over the frames. Would that make it narrow gauge - for 3' or 3'6"? That's assuming it's 4mm scale. Edited September 26, 2020 by billbedford Link to post Share on other sites More sharing options...
