That reminds me of an upscale Savage 219. We had one back in the 50's in .22 Hornet. I forgot who owned it but it was a loner. The brass did not last for handloading as the Hornet is not good at that. Legend has it that one guy hit a crow at very long range with it. Luck of course.

I would not put much effort into that gun however to each his own. Falling block SS's are of more interest to me. Even a rolling block but not a break open SS.

Those break open rifles always seem to have headspace problems.
