Thanks Cold Zero
There are actually some Serial Numbers here that expand the range of what we thought were known numbers.
As LE has noted earlier, it's getting clear there are a number of 1944 dated 74L0xxx range Snipers, and a number of 1945 dated in the 71L5xxx range. This hints that many of the Snipers were set aside awaiting scopes and pulled off the shelf using the First In-Last Out (FILO) or Random Selection inventory control.
All the data we can get helps understand the mystery
Could you just recheck the above numbers, which, if accurate, change our thinking about the 90L block (which heretofore was all 90L 80xx)
Thanks for taking the time, Robert
