your Remington rand was made in 1917.
1945
That is not a serial no of a Remington 1911A1 they stopped in 1945 with 2465139.
1943
In 1944 by Remington Rand
That should be a 1911A1, made in 1943.
Your 1911A1 pistol was made in 1944.
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................
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.
Yes and no. Remington Rand merged with Sperry Gyroscope, then split into Remington and Sperry Rand. The computer division Univac was transfered in the split from Remington Rand to Sperry Rand.
value would depend on overall condition....................
