I find it hard to believe WNr 1398 was both w/o (or even only damaged) on 16/2 somewhere in Russia, get back to Germany in the same month, and get converted to a P-1 by the next month, so if the docs you quote from are correct, what was damaged/written off in Russia together with the 88, 3527?
Just curious...

Cheers
