FWIW, I have 500188. 10ga Mag(?) frame,,has the lug cut out on the bottom.
Field grade, extractor, factory SNS trigger. F & M chokes IIRC.
I bought it as a parts gun as the rib has been D&T'd back near the breech end for ??. The receiver polished and cyanide colored and a jack-knife inletting job done to a replacement stock and homely BT forend.
The BBL is probably supposed to be 32" but IIRC it's 31 3/4" or some such off length just short of 32".
Now you know why I saw it as parts,,but I never needed to scavanged any off of it.
Suppose I should do something with it..would make a nice skeet gun for me.
Maybe a little upgrade is in order..shame to have it go to waste.
