where can I find HO 1940's fire trucks? - Model Railroader Magazine

1925 Aherns-Fox Fire Truck  

1924 American LaFrance Pumper

1923 Mack Aerial Ladder Truck

1913 Model T Fire Truck

1940 Ford V8 Sedan  -could be Fire Chiefs car.

 7/6/17 above links were for Jorden Products which are no longer made and not available from that seller.  Might find some on EBAY  

While these may seem to be a little old for the 1940's. Fire aparatus is very rugged and also expensive so usually well maintained and kept in service for a iong time.

The Model T could supply parts to bash a latter truck.

The Aerial Ladder could be "modernized" with a latter tractor.  I've seen a photo of one with a latter tractor still in service in the 1950's.

All of the above could provide parts for bashing latter vehicles.

I tried to sell my two cents worth, but no one would give me a plug nickel for it.

I don't have a leg to stand on.
