According to Ned Roberts - Ken Waters 1967 book, the Wurfflein match rifle was made in 22-15-60, 32-35, 32-40, 38-55, 40-70 Ballard, and other center fire cartridges including everlasting ones.  Also in 22 RF and 22 WRF.  Looks like you got a jewel.  When in doubt, chamber cast and slug the barrel.

The rear "hammer" breaks the action; the front hammer is the real hammer.

Also, for what it's worth, these guns are precisely (hand?) fitted.  For example, the barrel-action pivot screw is a serial-numbered part; it starts to eccentrically tighten up just before you fully drive it home, presumably to help keep it from backing out under use.

In my estimation, it's really a shame that Wurffleins were apparently only regionally popular.

As far as I know, no one has ever done a "body count" on surviving Wurfflein tip-ups.  I can't even tell you if the pistols and pocket rifles built on the same action had their own serial number ranges.  But I have never heard of one with a 5-digit serial number and suspect from my own research that no more than 5000 were built in all configurations and models.

All that I've seen were all very well fitted and finished; and while the majority are relatively "plain janes", quite a few have deluxe wood, some are finely engraved, and like the Maynard, a fair number of multi-barrel sets are known.

Again judging by my own collecting experience. they are not easy to come by today; indeed, even really big gun shows seldom have even a handful on offer.  But here's the good news.  Wurffleins are a perfect example of the truism that things which are rare are not always valuable.  That is, so little is known about them and so few people seek them that quite often, as in the case of mine, you can buy a very nice one with a shootable bore for under $500.

Wurfflein’s shop was somewhere in Philadelphia.  There was a Wurfflein Rifle Club there that sent its match scores in to Shooting and Fishing.  Everybody in the Club shot Wurffleins, and it may be that Wurfflein provided the range as well.  The rifle itself didn’t get a lot of press, IIRC; certainly some mentions and some regular advertising.  I got the general impression from my reading that the rifles were ever less frequently encountered the further one got from Philadelphia.

I found only one in my price range long ago.  A .32-40; everything there but the finish, and the bore certainly shootable.  But it seemed kind of loose and shaky, so I passed on it.

It's interesting - Wurffleins not frequently discussed by collectors - very few articles about them - very few advertised for sale and believe not one match shooter uses one because they are an accurate shooting rifle. I have only seen one, at the Maryland show and he wanted $2000 for it - zero engraving & no vernier

If a little over 5000 were produced ... where are they?
