Beware of scammers.

Virginian, Thank You for your information.I'll pass it on to my friend Ken.

I have a friend looking to buy a Remington auto-loading shotgun. He asked me which is better the M-1100 or M-11-87, or what is the difference between them. Being a collector not a shooter, I couldn't answer him.
I assume parts are readily available for both. Will 11-87 barrels interchange with the ...

I'm sure he is talking about the background in your second photo.
Very nice '75 however.

Every thing stated is very interesting, but doesn't explain why it was first sent to Remington-UMC before it's
world travels. Might I suggest that it was sent to UMC for cartridge development and function.
Then forwarded to either Colt or directly to Canada, Just my guess?

Researcher,
I know the "2" stamp is for a replacement Barrel and assumed it was done by Remington. Your explanation
makes sense. Thanks for the clarification.

I don't know if this will be helpful, but I have an American "Browning 3 shot" (marked on the fore end).
It's a 20 ga. S N - C8693. However, it has a Remington vent rib barrel. It is date coded DMM-2= 8/43,
which indicates it is a factory replacement. So not much help in dating it. It also has a ...

Ward's Collectables just had an auction that included over 150 Remington 22 boxes and tins.
This might help identify and value yours.

I have never seen or heared of a 700 with an 18 " barrel, other than yours.
The Blue Book lists 700 Carbines as being made with 20" barrels in 1962 & '63.
I would say it's a custom barrel, done by Remington or someone else.
Are there more than one set of date codes on the barrel?

Tom,
It's a very nice piece of wood. Are there any markings on the Butt plate or Grip cap?

I agree with Researcher. It's probably a training shotgun. If it was a combat shotgun it would have a shorter barrel.Is the barrel serial numbered to the receiver?

While I never met Ken in person, I talked to him several times on the phone. He was always willing to share his vast knowledge of Remington CF Pump rifles. I have to say The Society has lost a valuable resource.
My condolences to his family and friends. RIP Ken!

I can't help identify the case. My best guess is, it's custom made, and could have been done by anybody with wood working experience.

In order to answer your question, we need information as to what kind it is.
Single or double barrel. If single, is it a pump or semi-auto?
Posting a photo would be the best, along with the serial number.

Don,
I'm positive this is a cut down Remington Carbine not done by the factory. Someone heated the tangs and bent them for a pistol grip. Then made the grips and fore end.
The barrel may be the cut original or a replacement. What is the caliber?
I had a Model #4 Rolling Block that was modified the ...

I would say the RR code dates this as November 1968.
Also it appears that it is chambered for 22 shorts, and would be considered a Gallery rifle.
