First flat car with load from MTH

I was an early MTH customer,even before it was MTH . My guess is it was the Caddies but I can not say for sure. I know I have the car somewhere. The auto loads were very popular.

thanks Dale someone said it was a gray flat with an Ertel backhoe,which was before any Flats with cars trying to find out if that's true 

I believe it was in a starter set that had the backhoe on flat as the first one. I always liked that car ...

The flat with two caddies was the first flat with autos.

Thanks picture of the set was very helpful 

When I bought the set The guy that owned the store traded me two new mth freight cars for it. At the time I thought it was a good idea. I guess it was not?

I don't know if was a bad deal because not to many people know that was the very first flat with a load , most think it was the Caddy and there not worth what I paid for them years ago either matter a fact most MTH stuff not worth much anymore. So now all my ps1 engines get run and all new stuff will be post war Lionel 

So was the reason my dealer wanted it was because it was a flat car or because of the bockhoe
