Gentlemen,
D& B have just provided me the serial numbers for the drum mags they are selling with, or without, the P-Kasten.
140318, 325142, 106352, 370124 and 193103
All appear to have one thing in common, and not just the price, £1495; and it is thanks to members on this forum that I gained that knowledge, so big thanks to all concerned.
They never supplied the requested photos of the markings on the Loader.
Richard
