A34, welcome to the forum. I am restoring 3,884,956 only 7,787 newer than the one of your buddy's. IBM was producing about 40,000 per mo. I have been told mine was around the end of Feb '44, right in the middle of T.R.'S guess-t-mate. Look up the thread on IBM slides 2-12-10. If you can post some pictures that would be great. If it has not been redone, I would like to see the shade of park, and witch parts might be blued. HTH.....Frank
