I don’t recall having posting this before.
I have assembled a collection of 275 U.S. patent documents on lock picking devices. This collection is as complete as I could make it & covers such diverse topics as lock removal, code finding keys, decoding instruments, key cutting, and so on. The patents are in pdf file format on CD, so a computer (Mac or PC) with a CD drive & Adobe Acrobat Reader or equal pdf reader is needed. Patents are full image & can be printed.
I am blocked from listing this collection on eBay due to their rule against anything related to lock manipulation.
Anyone interested in getting more information can PM me.
