Nice catch and looks like it was well done. But, while the snubby conversion was certainly done in a similar style to the Jovino guns, I've never seen anything about the Jovino gun shop doing caliber conversions. There were any number of gunsmiths doing snubby conversions back in the day, with the Jovino gun shop and Austin Behlert being two of the best known. And, as mentioned, M28 big bore caliber conversions were common, heck, they're still being done, I have one out being turned into a 3" .41mag now. So, while it's obvious that it was a skilled gunsmith that did the work on that particular gun, it probably did not come out of the Jovino gun shop.

I'm also looking forward to your range report.
