For those who did not see Frank Major Tobin's gun, here is the gun, finished in Pyro Oxide, a special add on. ![[Linked Image from i.imgur.com]](https://i.imgur.com/u1CH6mv.jpg) Beautiful gun but what is pyro oxide? Is that another name for charcoal bluing?

'Pyro-Oxidized Black' was introduced with the Black Diamond Grade No. 55 in 1908 ![[Linked Image from photos.smugmug.com]](https://photos.smugmug.com/US-Makers/Tobin/i-xbXr6M6/0/MTmkXc2DxnwdZwL5N5nF4GsbPGXLjqjMv53V8FkDW/L/Tobin%20No.%2055%20Black%20Diamond-L.jpg) The No. 20 Simplex first had case hardened lockplates, but I believe later the same process which I've never seen described.

Not positive, but, it may have been the hot version of black oxide: https://en.wikipedia.org/wiki/Black_oxideI bought a black diamond 12 gauge from our own John Mann, longer ago than I care to remember. It was a durable finish, unlike the cold version of black oxide. A friend still owns that gun. Best, Ted

That Black Diamond Model sheet is from my Tobin catalog collection -- ![[Linked Image from i.imgur.com]](https://i.imgur.com/omS1UXP.jpg) My 12-gauge Black Diamond -- ![[Linked Image from i.imgur.com]](https://i.imgur.com/OoyCj3Y.jpg) The Black Diamond was the first Tobin I got. Found it at the Rockingham County Fairgrounds gun show in the Shenandoah Valley in the spring of 1988. That gun and the Tobin ads I was finding while researching things Fox at the Library of Congress and feeding the info to McIntosh for "The Finest Book in the World" as Headrick nicknamed it led me down the Tobin rabbit hole!!

That is an awfully nice Tobin. It is really difficult to find guns like that.

That black oxide treatment on Bakers was from the 1913 to 1919 period. Then , after Baker sold the gun making part of their business to Folsom in 1919, the black oxide treatment was used on the grades above the Batavia Leader. Those grades using the black oxide , or similar, were the Black Beauty Special, a few single barrel trap guns , Paragon ,and the DeLuxe. As I recall the Expert was advertised that way, but I have never seen an example.
