You're welcome Mike!
I know it's not the exact same gun, but Marlins didn't vary much in design, and I figured like me, pictures are worth millions of words when trying to figure out how it all fits back together.
I got handed a basket case too, one I didn't even know existed. A Squires Bingham Model 30 pump 12ga made in the Philippines, I "think" back in the 60's. By the looks of it, it hasn't been cleaned since then either.
I usually don't take in a basket case, especially one I'm not familiar with. One of those deals where it's a favor for a guy, that does work for an elderly lady on her ranch, and she's always finding me great deals on old guns. Yeah, my arm got twisted.
