A company called Modeltorque in Australia that now no longer exists, and another company in Ireland whose name escapes me, made/make these motors fitted with a bracket with fixing holes that line up with the screws that hold the cover on a Ringfield type motor. The motor Mike has used doesn't appear to have any bracket.
No I'm not John, apart from small ish locos I'm also collecting heavy goods, 0-8-0, 2-8-0, 2-10-0 etc. Got 5 9Fs, 3 ordinary and 2 Crosti's. Naughty but nice.
Bulver GWR/WR steam locos are very easy to rename due to the fact the numbers are on metal plates. You just buy a net of name and number plates and stick them over the originals.
