A High Wall at the right price would get my attention, obsolete caliber or not. Highs Walls were very much in demand by wildcatters and were a strong action for some pretty high intensity varmint cartridges. The supply has all but dried up because of demand by collectors and people who used them for custom conversions.
Recently, I bought a Hopkins & Allen model 932 falling block rifle in the obsolete .32 rimfire chambering. The price was right and condition much better than average. I'm trying to decide whether to keep it original with little chance of finding ammo at a decent price, or making a new link so the falling block firing pin will hit the center fire primer of a .32 S&W long after a little chamber reaming. It is a relatively simple and economical conversion. The bore is excellent and it would make a nice falling block squirrel rifle. It could also be relined and chambered in .22 rimfire. An obsolete caliber does not mean it is destined to be a paperweight.
