Serial number is S820xxx = 1945
At least for shipping, not likely . . .
S-series revolvers MAY have been in manufacture in late 1945, but nearby S-series SNs on my list all appear to have been shipped in June and July 1946

shipping, I agree with 1946, but the OP was interested in manufacture date and this one could have been in 1945
I'm in agreement with both these guys,
BUT keep in mind that military shipments of SV revolvers lasted until August, 1945. The war ended that month. There were quite a bunch of SV marked frames hanging around at that point and they were later assembled for civilian shipments. The first gun without the V as part of the prefix was S811120 and it was assembled on September 12, 1945. Quite a few more SV guns had higher serial numbers than that one and the S and SV guns were built up concurrently for some time. The highest SV number I have been able to locate carried serial number SV813132, and it went out the door on April 4, 1946. There are lots of S guns with numbers lower than that one. Also, shipments seem to have virtually stopped between August, '45 and March '46.
One noteworthy point is that most of the guns shipped in the spring of '46 that I've been able to identify had the commercial blue finish, regardless of whether it has an SV or S serial number. I suspect that the hiatus in shipping had to do with a transition from wartime guns (with the matt finish) to the early commercial guns, many of which had the lanyard swivel hole plugged.
So, yes. At least some of the early S prefix Military & Police revolvers had frames that were forged in 1945. But I doubt we will ever know how many. All we can know was when they shipped, and there is lots of evidence that they did not start shipping until March of 1946. (The big exception was a shipment to the Cleveland PD, which went out in February. Most of these guns carried S815xxx serial numbers.)
Incidentally, the S820xxx guns seem to have been orphans. There is evidence that many, if not most, of them left the factory in late spring or early summer (June & July). But I show several guns in the S823xxx and S824xxx range that shipped sooner - April and May of 1946. I don't show a single S820xxx that shipped before June. Odd.
