Parker 10gauge hammer gun
 

Not sure what I have frame wise or about these sites or value any help greatly appreciated. Thanks

Interesting. It looks to me that the buttstock may be a later factory replacement. But I cannot tell for sure based on the little that I see. And it was likely being used for slugs or ball with the rear sight that is installed. Aftermarket of course.

Front sight is blade type
 

1876 according to serial number

The frame size is determined by the distance between the firing pins.

Could you show us pictures of the rib engraving and the water table. Thanks

If these are not good enough I’ll take more when I get home

Getting a letter on this parker

1 1/16” is distance from center of firing pin to center

Don't bother, the info for this gun is unreadable.

Well already paid for it can I get a refund lol

Absolutely. Did you order a research letter online or did you mail me a check? Either way you'll get your money back.

Paid thru pay pal 6826 is serial number

Here is the measure meant of firing pins which frame is this. Many thanks

My engineering background would tell me that this is two sixteenths, not one.

Measurement starting point is suspect. I learned more than once (yes, I’m sometimes slow) not to trust the end of a tape when taking critical measurements. Start at the 1 line and see what you get.

I did it’s in the other post

Then please disregard. I did not see the other post.

I was about to make exactly this comment. I have seen many pictures posted lately using this technique. The only time I ever would do this when marking or measureing a long board with no help. Then only on rough cuts. For measureing down to 1/16ths, you should use a caliper or at least a decent quality scaled rule with a marked 0 line. Or do as the post says and use one of the marked lines as a starting point.

Absolutely. And, in the interest of fairness, and honesty, I will admit to making the very accurate cut, only to find I'm one inch short. ( I have a great memory. Short, but great)

You want more exact use calipers and measure right side of one hole to the right side of the other or left to left . Trying to figure center points is a crapshoot at best .
