Too bad, I cannot attach quick pics here, but eg. in the 17 VA's April 1, 1945 AC inventory ALL Yak-9s between 2515380 - 5415377 (including two from the 27153xx series) were Yak-9M model! They simplified/unified the airframe production in the 'M' (modernized) version after batch No.25, because the location of the cockpit of the main 'D' and 'T' versions were in different spots in the fuselage. Thus maintenance and repair was difficult on the frontline airfields, so after batch No.25 they just built the 'M' version.

You are probably right about the “M” as I have not dealt into the factory make up. The location, time and circumstances of the loss of Lin’kov though is correct. Does your book include any of the claims for the Leningrad sector in 1941?
