I just don't think that's a Remington made 1911A1 Serial no, are you sure it's no mixed parts? May be Colt, 1924................
your Remington rand was made in 1917.
That is not a serial no of a Remington 1911A1 they stopped in 1945 with 2465139.
In 1944 by Remington Rand
Your 1911A1 pistol was made in 1944.
I thought that would be in the end of the serial range of Ithaca but 1944.
That Colt was made in 1943 by Remington Rand under cotract to Colt Mfg. Co.
Your colt model 1911a1 was made in 1945,plus the serial number puts it in the range of the Remington rand numbers in my references.
Model 1911a1
Early 1911
Manufactured 1909
A serial number that high could only mean a government model 1911 or 1911A1 .45 cal. that was made in 1943 during WWII(1279699 to 1363699) by Remington Rand.
RW is Remington Works, not part of the serial no. 1912.
