GWR logos (current)

[davidinyork]

Does anyone know whether etched GWR lettering / logos, as seen on the real Class 57s and some HST power cars, are available in N-gauge from anywhere?

The real ones appear to be stainless steel - all three 57s in the standard GWR livery have them, plus some of the HST power cars (the earlier repaints into the livery - later ones have vinyls).

Thanks
