6.6m WRA Carbine build date?

I’m trying to figure out the approximate build date for a WRA carbine, 6.600xxx. I know the WRA polish room dates are available for Garand receivers and wondering if the records were also found for the Carbine? The books I have and charts on line indicate blocks of dates and are not very specific, for example this one would probably be Jan45. However, when I find a few close numbers on line the experts say early mid 45. Just trying to pin down a better date, my guesstimate based upon what I’ve found is Apr/May. Can anyone on the forum provide a more definitive or accurate timeframe? Regards

The last serial # applied on a WRA receiver on 8 May 1945 was 6600370.
The last serial # applied on 9 May 1945 was 6601750.

Keep in mind there was a time lag between the date the serial # was stamped and when the carbine was a finished product.

Thank you very much that is exactly what I was looking for. This is 670, 9 May. Regards

Thank you for the great info, could you provide the serial window for 23 April? I have a WRA Garand that was serial numbered on 23 Apr and while doubtful it would be interesting to find one serialed the same day! Thanks again.

cpc,
Assume you are talking about Apr 1945?
The last serial# applied on 21 Apr 1945 was 6581550
There is none listed for 22 Apr 1945 (Sunday off?)
The last serial# applied on 23 Apr 1945 was 6583020

Thank you very much - now I will be on the lookout for a M1 serial numbered between 6581550 - 6583020. Thanks again for your assistance and help! Regards
