The top gun part in each picture is the Folsom gun. The middle one, with a 49000+ serial number 16 ga, I believe is about a 1919-20 Baker Gun Co. gun possibly assembled by Folsom and the bottom one 100000+ serial number is about a 1910 12 ga, I think.
WHAT I MAINLY WANT TO KNOW IS WHETHER THE 16 IS A BAKER OR FOLSOM GUN AND APPROX. DATE OF MFG.
These two pics show different lumps for each one; the two 12s being almost the same; the 16, quite different also with a fine crosshatch on the bottom.


This shows that the 16 ga does not have the firing pin retaining screw; the other two do. Atleast, I think that is what it is. Also, each one has a little different thickness of triggers.

This pic shows the different sizes of bars. The bottom one, the old 12 ga with twist barrels measures 1.589 across the knuckle; the top one, the Folsom 12, measures 1.489. The middle one is the 49000 number range and a 16 ga. a little different shaped that slims further back than the 12s and it measures 1.265 at the knuckle. Bottom receiver has a three way safety.

This one shows the Folsom has a different rib and the 49000 range 16 rib has 'Baker Gun Co., Makers, Batavia, N. Y.' on the rib.

This one shows a little difference in the forends with the oldest one having an ebony tip.
