At the weekend a mate brought his newly purchased GWR green Terrier over for me to fit a sound chip into it.
I should have got a photo really, but we had a little line up of the following loco's:
Dapol Terrier,
Lionheart 74XX Pannier Tank,
Minerva Peckett,
Scorpio 58XX painted by myself in Railmatch GWR green.
All were different shades of green. I don't think that nowadays there's really a definitive GWR green. Even at Didcot all the loco's are different shades of green.
