Congrats! I have a six digit 870 in 16ga as well, not the deluxe model like yours, but I did find a Modified VR barrel for it back in the 80's which really turned it into a shooter.
Its like the 870s from this century aren't even the same gun...what a difference and what a shame.
They've definitely went downhill over the years. I've got a bunch from different periods but the early ones will always be my favorite
Nice Buy..... Those early 50's guns in that ADL configuration are all great guns......The Remington Pump aficionados refer to those as having "the 7 diamond checkering pattern" referring to the layout of the forend checkering.
My deadliest years as a bird shooter were my 20'and early 30's with 12 and 20 ga versions of the gun you snagged. Fit and finish were very nice and they slicked up really quick with use.
Even with a selection of fine guns , including examples of English and Italian "BEST" doubles, I still put in a couple of dove and quail shooting days with one or more of my 3 1950-52 20 gauges...... helps bring me back down to earth and reminds of my "raising" ..... They are wonderful pieces of Americana fieldcraft art, showing great form and function. Enjoy yours.......
Thank you. Definitely goes back to a simpler time. And you're right the more you use them the slicker they get
