I have now received some better photographs and superb provenance from the owner,being technically challenged I have emailed them to Captain Chris to be added to the thread when he gets a moment.
The original purchaser was a member of the LAPD,the provenace is in the form of a letter from GTR confirming the order and discussing handle material,also the original cashed cheque,very cool package.
The owner has confirmed the knives are not for sale but asked me if an idea of value for insurance purposes would be available,anybody care to venture a price range ?
