Guppy,
My sources indicate that as many as 150 H series Ta152s were built before the Russiand captured the Cottbus Works where they were built.
Here is an interesting section from my book:
There are so many different claims regarding the number of Ta 152s actually built that it's difficult to arrive at a definitive figure. It is a known fact that the Ta 152A was never built. Only a few of the Ta 152B and C series were produced.
It was a different matter with the H series, despite the fact that construction documentation was not available until March 1944. In a letter dated 18 July 1944 Oberst Petersen, commander of the Rechlin test center, expressed concern at the overly hasty introduction of the Ta 152. He saw danger for the H-series in the program's accelerated tempo. The fact that the Ta 152 production began with the H-series and not with an A, B and C version, as was normal, was cause for worry in and of itself.
