Lima: Thanks much. Will continue my search for a regular postwar-style powered B like the two Santa Fe units noted.
If someone knows of other powered B's like this, I would appreciated getting the Lionel item numbers so I can add them to my searches. I recall a dealer showing me a GN powered B like this once, but can't be sure and don't know Lionel number, in any case.
This is in reply to above chain, ending with:
Thanks, Lima. Do you know if a postwar F3 B unit shell will fit over a postwar-style modern F3 B chassis? (would like to use a modern powered TMCC F3 B unit, like the Santa Fe 6-14506 or 6-14517 B units) Those have a postwar-style (not scale and not "postwar scale", just plain postwar style) shell. Thanks...
Should, may have to install a plastic block for screw attachment or just leave them loose.
Have installed postwar Lionel shells on top of MTH Proto 2 F units and Lionel units with TMCC/Sound etc. We left the volume turned up and dropped it into the unit as Lionel's volume knob is a roof vent."
