Some time ago I bought a used lionel 6-11131 FEF but then sold it looking for a decent brass one correct for '46-'48. Availability not so much luck.
So I recently I re-acquired the same model but this time as old new stock and for close to half the price I sold my used one.
I figured at that price why not start with a fine Legacy locomotive and modify it.
Before I start fabricating the sellers system I figured I'd reach out to this forum to see if anyone knows if a part supplier already makes one and part#.
