Presume yours is the Euro version (i.e., faux wood metal case for 1996/German manual/test target)--- please verify!!! I have never seen a "KG " Euro--- could you PM me the full serial number (strictly confidential)???
Yes, though the case is long sold. I have one of the "surplus" K&K Air cases that was fitted to the Mk23s.
Serial is in the -271x range. I bought it for $996 in 1999 while stationed in Germany with the Army. It came back with me on a Form 6.
