"Dog Leg Hammer" - what is it? Do I have one?

[Promo]

When documenting my spare parts I also took a group picture of my M1 Carbine hammers. I've been told that it looks like there are so-called "dog leg hammers" among them. A quick research showed that they are differently shaped hammers.

With this I'd vote that the three in the upper left corner are dog-leg hammers. Is this right? And if yes, do they command a premium? And are they really only an early production step, which was later changed?

Thanks in advance!

You are correct. Three upper left and the rest aren't. Those are valuable...and nice shape.

photos show some early "dog leg" carbine hammers

Greater mass on the one hammer RCS, I can see why they'd need to pare it down and save the steel...and did.

actually that was what they call a "Fat Boy" hammer. there are two* types of doglegs, then the fatboy (technically the 3rd fatboy). The fatboy was used a short time followed by the introduction of the straight hammer.
they had issues with some early parts some they modified to for safety issues or breakage, others changed to save time. I believe the Fat Boy was to save time.
to determine type you would need to see striker face.
I would be interested in knowing the markings.

*depending on which system used

new2brass, which carbine manufactures used the "3rd variation of the fatboy hammer" as shown in my photo above ?

[Bruce McAskill]

Rock-Ola, S'G' and S.G. were reported as using some of these. Use of the Fat Boy dog leg only lasted a very short time but the standard type 3 hammer came into use.

Basically what Bruce stated. S.G. made their own hammers but do not think they made a Fat Boy as by the time they were up and running the straight hammer was in use. but may have had a transfer from Rockola with KR (made for Rock-Ola by Kal Machine) S'G' made their own hammers as well (yes same company, different locations) and as seen above did make the FatBoy hammers. These can bee seen on IP as well as S'G' . This was done after IP had lost its contract and being assembled by the Grand Rapids plant.
National Cash Register made them for Inland.

a Fat Boy

After all the discussion about carbines, finally a small detail comes out that I've not even heard discussed before. Interesting. And to find they aren't early as I'd guess, but almost like a trial part way through.
