Hi,
Yes, these most probably date from left-over Russian and Hungarian supplies that surfaced during the last decade. Most were sold off with cheap plastic grips (as the original grips had been discarded before storage).
A number of P08s, originating from these supplies were refurbished only a couple of years ago. These were refitted with surplus East-German barrels, reblued, fitted with Nill-Grips and sold through several large German gun shops.
The fact that they came directly out of storage and only needed minor repairs mean that these are usually in a much better (numbered) condition than most VoPo's.
An example of these reworked 'captures' is the 'Frankonia P08', still being offered for sale in Germany. They come boxed with a Mauser 06/73 manual.
This is an example of one:
