Stock Book Help

Don't know if this will help. But I just measured two of my hammerguns. Grade 2 16 gauge lifter serial 20121 0 frame is 2.060 across the breech and my 12 gauge top lever 1 frame serial number 26145 is 2.210 across the breech

Chuck, Parker hammer gun #15901, #2 frame 10ga, measures 2 3/8 across the bolsters.
#17895, #3 frame 10ga measures 2 1/2 across the bolsters.
# 9848 #2 frame 10ga measures 2 3/8 across the bolsters.
17895 might be in your book. I think your conclusion is correct, indicates frame size.

Thanks for that information Robert. It pretty much answers the question of what those numbers/fractions represent.

I was hoping someone would post dimensions of a 10ga on a 3 frame. Your S/N 17985 shows in the stock book as 2 1/2 so it correlates. Your 10 ga S/N 9848 and 15901, although not in the S/N's that have that info, being 2 3/8 would make them a size 2 frame and we know Parker made many 10 gauges on the size 2 frame.

I'm pretty sure the mystery has been solved.

Thanks everyone!

Chuck, You switched numbers. It's 17895, not 17985. It is a 3 frame 10ga and measures 2 1/2. I also have 51092, 3 frame 10ga, measures 2 1/2 as well. I agree mystery solved.

Chuck, What does the stock book say about o frame guns?
