I have been collecting hump backs for some time,JMB first took his A5 to Belgium to be made by FN! He then realized he had no market here,so he went to Winchester because they had made guns for him in the past!! They said not now,but thanks anyway!
He then went to Remington ,and the CEO and President of the company said HELL YES!!!
Then died of a heart attack the next day!!
So i think he bought the Company and Remington produced them (the mod 11 till 1948)so up untill about 1911 some remingtons were'nt marked Model 11!
They would be worth more,I have a Mod 11 made in 1930(26 inch barrel)that weighs about the same as my Browning light twelve!
I have another Rem Sportsman model(1935) it' s a thirty inch barrel(solid rib barrel)engraved with ducks on one side pheasants on the other!
I have the transition with the Rem Mod 11-48(no hump)big brother to the 870!
And then of course the Browning A5 light twelve(1957)!
Your shot gun was made by Remington under the browning patend!
When the War was on many Brownings by Remington were made to fill the gap(up untill 49 or so)!
The ones that were made from 1905 till about 19?? or so show the Browning picture of JMB and say made in Ogton Utah or such!! Worth lots more!!~
The ones that have matching barrels with the recievers that say Made in St lewis MO and nothing less also define thier age!!
If they say made in st louis Mo and montrial Qb,that also dates thier age!!
Even when the old guns show up with not so old barrels,they till command great prices!!
Cause just like that model 11 you have they are made from a single block of steel,and just the solid rib took many hours of machining just to make it!!
The recever alone milled by hand,and every thing about that shot gunwas hand fitted,it sold new for about 37.00!
To have one made anywhere near as close to tolorance as these fine old guns would cost you a fortune!!!
They are heavy and recoil ,and the forarms(wood )from the mod 11's will fit the Brownings(but not the reverse)cause the Rem uses a flat recoil spring,the Brownings use a round recoil spring!
I haven't tried changeing the flat springs to the round yet!
So yes it's probably a Rem 11 built on the Browning Patend!!!
