Yes, they've been out of production about as long as the original large frame Vaquero's been gone - or longer. For an (one) idea on prices, check Gunbroker not only asking prices--which tell only half the story (of what some are at least *wishing* for) but also look under completed listings. Look under a number of search cues. .32 Mag, .32 Magnum, .32 H&R, Ruger 32, etc. One caution if it matters, in addition to a birdshead model, the "baby Vaquero" came in two plowhandle type gripgframes, regular (aka "XR3 Red", same size as on the original/large Vaquero, other Single Sixes, and most Blackhawks) and short--made for youth, ladies and others of small hands. The latter was sold along side the regular framed guns and, for awhile, outnumbered the regular model. Ask which this is if you don't already know.
Great gun and cartridge--you'll love it!
