A quick question, and my pardon if this has already been answered, but when did the No.4 Mk.2 go into production in 1949? More specifically, in what month was the change over from doing FTRs on No.4 Mk.1s to doing FTRs on No.4 Mk.1s and modifying to No.4 Mk1/2 or Mk.1/3 configuration? My new purchase went through FTR in 1949 and was not modified, so I am curious.
