I have a "definitive" book on Czechoslovakian handguns. Here is what it says on production numbers and serial numbers. Working forward I calculate that your gun was manufactured in very early 1943, probably February. Below is the way the book lists production.
---Two years after occupation all vz 27 production was claimed by the German Military. Fewer than 5,000 had been produced during that period.
---Early 1941, all production was diverted to German War effort. Czech sources put the beginning serial number Of German production at #20500.
---Contracts for German Police began in late 1941. Production did not increase to any great extent, and by the end of 1941, still had not reached a total
of more than 42,000 pistols.
---Production ramped up quickly and in 1942, almost 100,000 pistols were made. (Total production to date, somewhere around 147,000 pistols since
German Military took over)
---in the peak production year of 1943 slightly less than 200,000 were made. Going on this and the above, it would seem your pistol was around the
31,000th pistol made that year of the 200,000 made. This is little over 1/6 of the production or the first 2 months of production in 1943. This would be
somewhere around February of 1943. This seems to fall in place as daily production reached 500 pistols per day in 1943.
---As a final note: Czech sources give the serial of the last pistol made during the Occupation as #473,000. This corresponds, almost exactly, with
known examples. However, most think this was a symbolic number. The total quoted production of vz 27 pistols for the German war effort was
approximately 452,500 pistols.
Hope this is helpful.
