Nice to have here John back. To Clemen&Jung piece it looks like correct finish not refurbisher or reworked so is not a repair, only small wearing spures there.The grips were probably reworked from the details on screws counter parts. I dont know how SS would became this bayonet, and why they would stamp there a property number with this form of DH in later of war? Thats why i mentioned my doubts.
To FP info about the engraving, i believe the engraving in field is very problematic, same as time costing, every Fieldrepair work certainly have a set of digits stamp as it was in army need to restamp serials by repairing pieces, is no way for me engraving 1534 crossguards so? With dies were easy to make any reserialing, same as i believe the DH should be too stamped. By engraving each skull is a originall. That could be realised only by small numbers.best regards,Andy
