hi phil,
if you allow me a a bit of time i will email drawings of what you require.
the john tipton GWR lamps are excellent and well worth buying as very difficult to make otherwise. for pre 1938 they should be painted signal red for all lamps. post 1938 front lamps were painted white.
here's the scale coupling on my own 57XX 5"g loco which is a heavily modified 'PANSY'
cheers,
julian
