Model 6 date of manufacture?

[CecilW]

I have a Model 6 with Serial Number S276937 located on the bottom of the barrel, just in front of the hand grip.

On top of barrel, in front of the rear sight:
REMINGTON ARMS--UNION METTALLIC CARTRIDGE CO.
REMINGTON WORKS, ILION, N.Y. U.S.A.--PATENTED JULY 22, 1902

I gather from other information on this site that it was produced prior to 1921.

Can anyone tell me when it was produced?


Thanks,
CecilW
