Mystery of the Missing Wartime Long Branch Snipers

[Seaspriter]

Is this a document listing scopes accepted during those periods?

No, unfortunately Marshall's report does not list scopes. The Report is referenced as:
Marshall, T.H. (1946) Small Arms Limited 1940-1946 (A partial history). Heritage Mississauga Research Files.

The full report can be found in this thread: https://www.milsurps.com/showthread.php?t=36140

Here is the annotated version just containing the Sniper references -- From the Production Records October 1943-March 1946 prepared by the Assistant Manager, T.H.Marshall , Small Arms Division, 1946.

1944: Total Snipers produced: 644 [Note: no reference to sniper production for 1941-43]
Q1-‘45 Snipers Produced: 254 Total: 898
Q2-’45:Snipers Produced: 24, Production fell due to not receiving the necessary telescopes, Total: 922.
Q3-’45: Snipers Produced: 161, with total production of this item up to 1,083 -- production was progressing in a satisfactory manner, compatible with the receipt of telescopes.
Q4-’45: Snipers produced: 58, Total 1,141.
Dec 31 1945: Small Arms Limited Uncompleted contracts: Sniper’s Rifle – 376; All assets and liabilities of the company turned over to the Department of Reconstruction and Supply and the company made application for the surrender of its Charter.

[RPL note: Total Snipers produced between 1944-1946 = 1,517]

To my knowledge, this is the only primary source we have. All others are secondary or tertiary sources. If anyone knows of other primary source data, please let me know.

Marshall's data, as it is more than likely very accurate, actually requires us to match serial numbers against production rates. Here is what (to me) makes the most sense, given what I've seen so far (still open to modification based on incoming data):

DATE---# Produced - Serial # Range (best guess)
Yr 1944---- 3----- 63L5
Yr 1944---- 10----64L7
Yr 1944---- 50----68L 350 - 68L 400
Yr 1944---- 581---71L 000 - 71L 581
Q1 1945--- 68----71L581 - 71L 651
Q1 1945---186---74L 001 -74L 186
Q2 1945----24----74L 187 -74L 211
Q3 1945----137--74L 202 -74L 350
Q3 1945----24----80L 8001- 80L 8024
Q4 1945----58----80L 8025 - 80L 8083
Yr 1946-----16----80L 8084 - 80L8099
Yr 1946---- 360---90L8000 - 90L8360
Total '44-6-1517

Remember, this matching system matches the production report to the serial numbers, but does not try to explain what grouping may be out of order because some scopeless Snipers were snatched away and sent to the UK to be scoped. I'm just trying to do the matching based on evidence, but it is still imprecise due to anomalies.
