It appears that in 1944 Remington Rand brought more Blanchard Grinders on line, prior to that they used Norton Grinders as that’s what was available early in the war.
If you look at the swirls found on the slides of 1945 Remington Rand production pistols these appear to be a direct result of the Blanchard Grinders. Blanchard machines produced parts at a faster rate, reduced the total number of operators required and were used for the manufacture of other parts even prior to being used on slide production. Alone the Blanchard milling machines had been credited in raising production from 1,000 to 2,500 pistols a day.
What I am trying to determine is when they started producing slides with the Blanchard Grinders. I believe to date the earliest RR slide with swirls on the slide is approximately 2,000,000.
I have included an image below that shows the swirls that are considered to be the Blanchard machines signature. Please feel free to email me with your observations at [email protected]
Highest reported Norton Grinder slide is 2,144,1xx (in my collection)
Lowest reported Blanchard Grinder slide is 2,179,2xx (in well known collection)
