once again, I thank the people of this forum for information supplied, especially with my English, it should not be always easy to read me

I know ebay and do not always appreciate the artificial bidders : Mad:
as all owners of milsurp, I have a big list as the arm of all the stores that can provide parts
but it is always good to share knowledge even Commercial
right here is my opinion

on my barrel, there are marks

DD (E) 24720/SK
D (with a half-bar across) 69 392 / K

and more forward on the barrel BB306

you know what it can match as manufacturer
I tried, but I have not found
sometimes too much information , kills information
