A plinker and a mystery!
You can blame the NRA for the first; the most recent issue of American Rifleman
featured an Iver Johnson Supershot Sealed 8 .22 revolver.
When I found one -- Model 844 -- at the
Tri-State Gun Show yesterday (hey -- they're open today, too!), at a price within negotiating distance of reality, could you blame me for being tempted?

It
is an Iver Johnson, with all that implies, but this example is in decent shape.

Best of all? Like the rest of its kin, it's a top-break! (FWIW: Iver Johnson also made bicycles and briefly sponsored Indianapolis-born champion rider
Marshall "Major" Taylor.)
...Another fellow at the show's got a long-barreled .22 Colt Police Positive that I really like; priced a bit high, though, and the sights are tiny, old-fashioned, sharp-of-eye-only: it would mostly be a "safe queen" and I have too many of those.
Next up, an antique-shop mystery:

Another top-break, with a very S&W-type latch and somewhat British hammer and trigger; I thought maybe it was an older S&W or an H&R (there's a small H&R in an obsolete caliber right next to it). Nope, the topstrap is marked "The Old Firearms Company" and there's a complex logo on the side.

Some island-gunsmith special? It looks too good for that, but I'm darned if I know what it is; even the chambering seems odd, something short and .45ish. Presumably not a "gun" as the Feds define them, but what else it is remains to be discovered. --By someone else.
