Real US patent office paper copies for traps and related fur harvesting tools

Description

From my early collecting days when I was more focused and driven. 112 plus or minus pages (copies) of original US patent office documents for various traps, smokers, fish traps and trapping related tools of the trade. Clean, clear, readable (one side) copies of documents and sketches of traps and trap makers you've heard of and some you haven't.  I'm surprised there wasn't more court cases for patent infringement. These provide some excellent information about old steel. Please don't ask that I check for a particular brand or style of trap. I didn't notice any Newhouse patents.. BUT.. I did see a very similar style double long spring with "hook in jaws" (like a 23 or 24). Shipped  for .50 via USPS, flat rate envelope.  Will provide tracking or certification numbers, once it's sent. Not responsible for fickle and often slow mail delivery times.
