I reached critical mass in my office and needed to purge some of the paperwork and piles of leather cuttings that have accumulated over the past year. I finally acquiesced to the use of a file cabinet, which meant I had to go through that too. I found some pretty interesting files ranging in date from the early 1920's to the 1960's. Most interesting to me were the customer lists from the 1940's.
I'm fairly certain that the confidentiality period for these has passed. Many of the customers here were using our Mechanical Leather (all for seals and gaskets).
