Hello!
Can anyone ID this cylinder? It appears to be .38 caliber, although the .38 special is way too long, and feels a little sloppy. Here's some pics. Thanks in advance and Merry Christmas to everyone!

It has the pre-1893 Belgian proofmark, and is almost certainly .38 S&W caliber, which is shorter and slightly larger in diameter.

hrf,
Thanks for the reply. I tried a .38 S&W round, and it still had a little play, but It wasn't as loose as a .38 special. I suppose that can be attributed to normal chamber wear over the years. Thanks again for your input, and I wish you and your family a Merry Christmas!

The cylinder is from a Belgian-made breaktop revolver. While it might be chambered for the .38 S&W if it was made for export to the U.S., it could be chambered for any of several European 9-9.5mm revolver cartridges, such as the 9.4 Dutch service cartridge, which would have chambers large enough for .38 S&W to be a loose fit.
