Your M/12 does not have several of the features of the F grade. I couldn't read the serial # but it should be engraved (like written letters). The stock quality and shape were definitely not with a M/12F grade. The fore end should not be grooved on an F grade. Sorry for this info, but....

Your M/12 was made in 1910. The steel mag tube is correct. Most were changed because of rust. My guess is that the checkering is not factory.

Look at "Manufacture Dates" on this site and the code giving the month/year of production is shown.

Model 512s had serial #s only through 1941. You can find two or three digits (letters) code on the left side of the barrel near the receiver that will give you the month/year of production. A total of 393,665 were produced ending in December 1962.

1946- Apparently fairly early in the year.

Rem made 14,266 Model 12s in it's first year. It sounds like yours has had a fair amount of use. My usual warning... Do not shoot modern hi-vel ammo in Model 12s. The M/121 replaced the M/12 and was made much stronger to handle the newer ammo.
Yes, the book is long sold out.

I believe that the sight will not work, but I'm not positive. The M/12 changed over into the M/121 in 1936. Many M/12s have been "shot Loose" by using hi velocity ammo. The semi's may not have been changed as much, but I would stick with standard velocity ammo.

There are CDs available for $30 ($25 + $5 shipping). The M/12 was (is) my favorite. It has 23 pages of info in the book.

There are a few nickel plated 12-Bs out there. A gallery gun with little wear is odd. It obviously wasn't used at a gallery. If the sights are plated it was not done at the factory. There are quite a few alternatives on the ones I have seen. As an example, some have the butt plate nickeled; some don ...

I'm not sure what the BJ4 is, but it is not the serial # nor the code to determine the month/year of manufacture.

The locking screw was used by Rem for a while. I can't find my reference material that tells when, but that configuration is proper.

The barrel length was advertised as 22", but slight variations are common. Yours appears to be factory.

Your M/12 was made in 1926. The forearm is missing.

Your M/12 was made in 1913. Does it have a round barrel or Octagon? Condition is king.

I'm back.....Thanks David....

Answers to your questions.

#2 yes
#3 Stock looks correct.
#4 I couldn't see the hole in question.

The ABS stamped rifles were early production. Approximately 1,500 were produced. The highest serial # we found was 1,482. Later production have Military Model stamped on them.
