There exist far better designs for actual use in the field then either a Tobin or Meriden (Klunk, MGRHS, was a Meriden fan, but, more for looks I think, then use) since stock dimensions, and metallurgy, came a long ways in just the few decades after Frank hung it up.
My own thoughts as to Tobins are, that the frames have too much material hogged out of them to leave them strong enough to use with modern ammunition. The Tobin design is neither sidelock nor boxlock, but a strange morphing of the two. The only thing carried on the sidelocks are the sears and their springs, the rest of the stuff, including the roller equipped mainsprings, that double as cocking rods, are inside the frame. I use mine, but, pretty much only in bluebird conditions with ammunition that is about the same pressure as the time period of the guns.
Roy pretty much nailed the pricing, again, in my opinion-dude can ask whatever he wants for his Tobin gun, it is beautiful, but, not worth that kind of money to me.
I'm guessing it will be for sale for a long time.
Best,
Ted
