This follow-up I submitted yesterday, to the repeated attempt to upstage Dewey Vicknair, must have gotten lost or something. So I'll try again. The new example pictured above is a bit better, and is beginning to approach Crescent Gun Co. metal fitting and finishing quality. However, if you are going to accuse Dewey of negative cherry picking, you should at least choose some nice cherries as examples.
I don't recall ever seeing a Crescent, N.R. Davis, Worthington, or any other cheap double with a screw slot as far off-center as the set screw on the left. The screw slot in the previous photo looks like it was cut with a hack saw. Screws on field grade Baikals look better. Cheap Chinese toys from the Nixon era had nicer screws. And look at the difference in the length of those ejectors! The peened ends suggest poor quality steel or a need for heat treatment.
If I made a gun screw like that and posted a picture of it here, I would be laughed off this forum, and rightfully so. I'd have my Liberal Gal Fan Club here saving it, and reposting it for all time to mock me. It is remarkable that anyone would post that image as an example of fine gun craftsmanship. I might also give that a "Like"... if I was a know-it-all who knows very little.
Stick to what you're good at... even if little more than collecting pictures and old advertisements. Leave the gun critiques to someone who actually has skill, extensive hands-on shotgun knowledge, and a discerning eye.
