Posted by As promised, I have updated my production estimates, based on the serial numbers I’ve observed since the last update. Click here to see my latest and previous estimates.
Since my previous update, I observed 33 new 1040 serials and 6 new 1041 serials. The biggest change seems to be ref. 176.002, which represents 12 of the 33 new 1040 serials observed. To help illustrate how the estimates fluctuate as I observe new serial numbers, check out this article I wrote a while back.
