I'm doing the usual rounds of book sellers but would be interested to know which of the 18/36/37 guns were used by the DAK ?
Do their active dates preclude the use of a '37 or were they in service by then ?
Peter had added quite a bit of detail, so I'm still looking through the manual to determine which bits are his and which are Armortek

I doubt I'll be doing any work on the gun till next year as there's so much to research first

I'll get it out into the sunshine and post a few pictures.
Adrian.
