Quoted:
That's a first model AirCrew Kappmesser, issued to all flying personnel not just paratroopers.
First model has bright blade, non-take down. They aren't easily repaired so they are somewhat rarer.
2nd model usually has a blued blade other metal. There is a push button to allow the hilt to be removed for cleaning or maint of the knife.
That example looks rather nice, I would think $500 easy if it hasn't been messed with, no polishing, replaced grip scales or ground blade or reground blade tip.
The blade is slightly bent. Looks like some one my have used to open a can or something. You can also tell its been re sharpened several times.
The grips appear to be original.
I was bummed out that my uncle got Granddads P38 he brought back. But these have turned out to be more special than I thought.
Thanks for all the info. They will remain in my gun safe, where they've been for the past 3 years.
