The only Dapol 6-wheeled loco I haven't got is a Pannier!
On the other hand, I've the black, unliveried Terrier, the recently reduced BR liveried Jinty, a black 08 and a couple of 14xx in black and green liveries respectively.
I'll have to build a layout for them to appear on, I suppose the best bet would be the terminus of a fictional "heritage" railway...
Fingers crossed that no more reasonably priced small locos turn up.
