We have some very interesting blue prints in the company collection, many of which were (allegedly) only made by certain companies. It seems Union Cutlery did a fair amount of contract work for other companies during the war. With the need to expedite some products this inevitably lead to the "sterilized" versions getting in to the hands of soldiers as companies did not have time to mark them and Union Cutlery would produce products unmarked as to not limit who they would be sent to. Stories would emerge that these unmarked products were made for special units, but this is a myth. Having a close relative that was in an OSS Operational Group and working at a WWII museum before KA-BAR, I have had the opportunity to talk to many members of these units. That was one of the first questions I liked to ask and was always told they preferred marked items as it helped their chances of not being executed on the spot as a spy if they could prove they were soldiers. Many of the OSS units would leave behind distinct American calling cards such as a pack of American cigarettes after attacks. Though we may be lacking in documentation for the early years of the company, there is an abundance of WWII-era paperwork and documents for Union Cutlery.
