I'm Stumped
 

I've got this graded hammer gun all taken apart and have sonically cleaned all the metal parts and as I was inspecting everything closely I discovered this inside the trigger guard bow. It is likely to be the mark of a worker in Meriden who worked on this gun.... or maybe not.

Hopefully someone may know what its significance is and what the letters really are. It looks like cpp. or .ddo but it is tiny and even with a magnifying glass I couldn't be sure.

Anybody have an opinion??

Hmmm.... Could it be cap. for Charles A. Parker?

Are they tooth marks from vise jaws?
That's my impression... (No pun intended)

My pictures could have been sharper but it was necessary to enlarge them by cropping. The letters are really tiny, about 3/64 or a shade smaller. If I had posted better pictures you would see that they are perfectly formed lower case d's or p's. I can't rule out the possibility of vise jaw marks but I'm pretty convinced they are letters.

Time to break out our hammer guns. I just checked mine Dean, (2) grade 2's and a grade 3. Nothing there.

Dean, the last 2 ate definitely "ap" then a period. The first looks t be a "c" or maybe an "o"

Look under the letters there appears to be a No 2.

No, that is a scratch. Thanks Wayne.

Dean---If you know of a doctor nearby that has a microscope---that will give you a clear image ---just might solve the puzzle !!

You can take the ocular off the microscope and invert it. Kind of like a jewelers loop, high quality.

Take a digital picture with the camera image set to raw format for the most detail. Then zoom in when its displayed and that should be as good as a loop.

By raw I mean.... http://www.techhive.com/article/1879...tal_focus.html
