again another silly question have a stromberg 48 body looking at the sizes it appears to be possible to build a 97 into a 48 by swapping the bodies has anyone done this and the results

The 48 base and 97 interchange so I don't see the problem. Uncle Max is the man to ask.

Look at the difference: Venturi, air bleeds. Not a good idea.

Rebuild it and try it, a little bigger in diameter 1-1/32”.

terry the venturis and air bleeds are all in the main body thats whats getting swapped just wondering how successful the swap is

The base is the same as I said. Now the 81's are different but that is not the question here.I can't remember if the butterfly shaft acc pump linkage is identical to the 97 (S & W).From what I remember the 48's only have 1 ball connection.

You are correct about the base. The pump rod for the 48 is shorter than the pump rod for the 97 / 81.

You can swap the middle bodies - not a problem. A true 48 base does NOT have the dual accelerator pump positions like a 97 does, and you can swap based back and forth. I've seen many combinations over the years - people swapped all sorts of stuff around. As Nick noted, make sure you have the correct length accel-pump push rod if you're running the 48 base. I actually prefer to use the 97 bases - as I like the adjustment. With that said, I always use the outward position - for more of an accel pump squirt.

All you have to do is replace the butterfly shaft with a 97 into a 48 and you're good to go.Stromberg has them new

Also, the choke setup is a bit different on a true 48 - the linkage, etc..
