Coach Joe,
Thank you for the comparison photos of the traditional vs scale FAs. I didn't know the difference was that great. I think, outside of brass importers, the only scale FA1 was the Williams model. All other scale FAs from Lionel, MTH, Weaver were FA2s. Since my layout era is pre-1950 (before FA2s) I will be searching for the Williams PRR FA1 version. Right now there does not seem to be any for sale. Rats.
