Made in 1938. I'd be more inclined to say about 1939 Listing I have shows 1938 starting with 9000 & 1939starting with 9550 so it would appear that 9412 to be somewhere near the end of 1938. I'm using R.L.Wilson book on colt dates of mfg. production ending at 9000 listed as 1938. Producation ending at 9550 listed as 1939.............we are in the right playing field, I think......................... I used proofhouse.com which like I printed shows 1938 starting with 9000. Have to see if I can find R.L.Wilson book.We are in the right ballpark give or take..... o.k. your turn at bat.............
Rifle or pistol?
1911
No way to answer without the serial number.

Around 1931
about 1920
about 1906
@ 1972
The caliber of this weapon is .45 ACP, or it's full name is .45 Automatic Colt Pistol.
A Colt 1908 hammerless .25 with that serial number was made in 1914.
To answer the question we'll need to know more about this pistol. Is it a revolver or a semiauto? What model and caliber? I found a Colt frontier scout .22 with that serial number made in 1962.
