Beware of scammers.

I agree with Mike, This 513 bolt handle is different than the other 500 series 22's.

If the barrel is serial numbered to the receiver, it's a good chance the date code would be correct.

Steve,
I noticed your Derringer is 100% nickel. The typical Remington nickel ones had the hammer, trigger,extractor, and take down lever blued. Thus yours could have been refinished. I'm not saying t is, just that it isn't what we normally see.

Steve, I was going to say Dan didn't have his glasses on , but I'm sure it was just a typo. His production information is correct. Your O/U is a 4th Model 2nd. variation. Also KZ is May 1931.
I also have an opinion on the derringer itself, but feel an unsolicited comment isn't proper.

Hi all,
I hope to clarify this 510-610 confusion. Remington experimented with a higher powered rim fire cartridge, the 267RF.
I don't have the book handy, so I can't give the dates. However the few examples they made were in the 600 series.
The 610 single shot, 611 clip magazine, 612 tubular mag ...

Remington discontinued barrel marking codes from 8/'99 to 10/01. Like yours mine doesn't have a visible date code.
However they still marked the shipping boxes with the code .
The box for my Etronx 22-250 SN EG000536 is date coded 31AU 3/2000.
This probably won't give you the month, but ...

All of my lite weights are gone, but as I remember the BT, TWB, and CWB all had chrome triggers, magazine tubes,
and silver or gold colored sights. They also had blond wood with checkering.
That's as I recall.

We need a lot more information to help you.What type of rifle are you talking about?
Bolt, pump, auto? As Admin said a photo would be best

Duke,
I just now noticed your post. Where is the "RW" located and is it stamped or engraved?
The early M-12's had the serial number stamped on the front underside of the frame and RW was just above it.
I believe it stood for Remington Works. If this is the location of your RW, then I believe it isn ...

For general information as well as prices, I would recommend "The Blue Book of Gun Values".
All of your arms would be listed with basic information.

I believe these were dealer promotional advertising signs from 1958 or '59.
I base this on the fact that the M-725 was introduced in1958 and the M-740 was discontinued in 1959.
I doubt they would advertise a Model that wouldn't be available.

Are you sure this is a 612 and not a 512? The Model 600 Series were experimental, and chambered
in 267 rim fire, not 22rf like the 500 series.

As I recall the M-25 butt stock is closer to the M-12 then the M-14/141.
I no longer have a M-25 to check the size.

Donald M. Simmons published an article on "Remington Model 51 Prototypes" in the May/June issue of Man at Arms. While the ejector magazine is a feature of the prototypes,it could be exchanged, and thus not a guarantee of a prototype. While there were several differences from the ...

I assume you are talking about the set with a hunter-1912, wolves-1909, bear-1907, and quale-1917.
This set was advertised in a 1978 Remington catalog. If they were made over a 4 year period, there probably were several printings, which could explain the variation in the color and paper.
This is my ...
