The DE63 S-92 is the 5'th of 6 variations of the G Date Luger...

This could be a desirable variation based on the numbers produced, and it looks like you have 2 matching mags which is very desirable. I'm no expert, but, IF everything is correct with the gun and mags, I would think maybe $3000 and up? What say the experts?
