Hey! That's
MY gun!
Okay, okay... I'll talk. The hammer on that particular gun is of MGW make, and, no, it is not an old gun. Although it is an Ithaca slide with a S&W sight, it was very recently finished by my gunsmith, Dave Sams. Maybe 3 months ago IIRC. Here's a link to my original post:

The thumb safety was originally left in the white, as it turned orange in the bluing tanks even after acid etching. It now matched the rest of the gun since Dave put it in his stainless tanks.
The Ithaca and Springfield:

If you look at the post that photo came from, you'll see the Springfield Dave built for me as well, and it wears a VERY similar looking hammer that is actually a Colt hammer that has been reworked extensively.
I have used the King's part also, and I have found all to be very good. If you can get an older Colt hammer (Series 70 or earlier), do it. I have that style hammer on My Springfield, the Caspian/Ithaca gun, and my Delta Elite. The Delta is the factory hammer for that gun.
The Ithaca has a very sweet, short 2.5# trigger, and the Springfield is a very crisp 4#. If you talk to Al Shear, I'm sure he'll let you know what can be done with actions using these hammers.
I hope that helped.
