Something different that caught my eye...
 

A couple days ago I stop by our local gun shop on the way home from work and saw this. The owner/friend usually gives me a good deal, and he did. Took this Tobin 12 out today and tried it out. Had a good time, just wish there were more birds. I regret missing the ones I did while getting use to this gun. I'm dialed in now, this was made for long shooting. Can anyone date this? I'm thinking 1904 - 1909? #4443

Trojan Nitro Steel was used on the Standard No. 20

Thanks Drew

The Black Diamond Model was not shown in the 1906 or 1907 Tobin Arms Manufacturing Company catalogs. It was introduced in this flyer --

So far your gun is the lowest serial number Black Diamond Model I've recorded. What is the barrel length for my table of observed Tobins?

As Dave said, you've got a Black Diamond Model from 1908-1909. I just bought a 16 ga 28 in. bbl in the 7000 serial range from a member here and am very pleased with it. Dave, pm me if you want the serial number.

I wasn't sure if it was a Black Diamond. Shoots well, even has cast off. Thanks for the info guys!

There is a Frankentobin on GI now that appears to be a Black Diamond frame with all the other parts from a No. 45E Premium Grade serial number 8452 installed on it?!?

By the way. What is going on here?

None of my Tobin guns have that?

Good catch, I thought it was a pin. I thought maybe there should be a screw there?
