The closest semi-equivalents manufactured in recent memory that I can think of:
The Mexican-made Mendoza pistols. Stamped frame, single-shot 'Rolling block'-type action usually chambered for RF ammo. I have seen examples in .22 RF, .32 RF Long, and 9mm rimfire shotshell. Don't know if they were ever legally imported, but you used to see a few of them in S. Arizona back in the day. IIRC, they used to sell for the equivalent of about $10 US in the border towns.
The Garcia "Bronco". Made in .22 RF single-shot, .410 bore single-shot, and .22/.410 OU. Very basic, fairly rugged, and cost about $50, IIRC.
The Sheridan "Knockabout" in .22 Rf. Single-shot, tip-up action.
The Savage 101. Single action, single-shot. The 'cylinder' swung out to load and it looked very much like a SA revolver otherwise. Not made of castings or stampings, IIRC, but both rudimentary and inexpensive.
The 'class' of the bunch, the Springfield M6 "Scout". .22 RF, .22 WMR, or .22 Hornet/.410. Top-break OU with mostly stamped construction, modeled after a former USGI pilot's survival pack arm. About as 'basic' as it gets, but extremely rugged and astonishingly accurate with .22 RF, once you master the rudimentary sights, slow lock time, and squeeze-bar trigger. If they'd actually been able to produce and sell them for as little as they looked like they ought to have, they'd still be around.
