A .22/32 thread! How could I not participate.
Here's one of the last .22/32 target revolvers shipped before WWII put an end to commercial production: no. 533038, shipped January 1940.
The later labels don't say anything about "Bekeart" or use the phrase Heavy Frame Target.
It's interesting to see how the company described this offering in its catalogs (1925 in this case).
I don't have a photo of the open cylinder showing the recessed chambers, but you can see from the tiny gap between cylinder and recoil shield that this cylinder enclosed the rims of inserted cartridges.
