Very nice!!
But, Series 70 has nothing to do with it.
It is a military 1911A1 made by the Remington-Rand typewriter company in 1945.
25 years before the Series 70 Colt was thought of..
The M1Carbine bayonet is nice too.
Who made it??
PS: Your R marked mags were made by Risdon, not Remington-Rand.
The L marked mags were made by Little Mags.
All are period correct, and correct for the Remington-Rand pistol.
