There are addition pages to the page you see at the beginning of this post.Those pages explain how to cut the codes with a drawing, and also pages with codes. As far as I know nobody else has those pages. I do not intend to release those pages until at some point I stop cutting the keys. Since this was originally posted Pitzer retired from cutting the keys and I took over. I generally only cut the keys in brass but do have a machine and ability to cut them in steel and do have steel blanks. Yes it is expensive as it takes a lot of time to get right. Certain keys cuts are much harder then others. As for the reason they are no listed by state,how could they be? The Bell system was not in every state. The Bell System was in regions. You determine the location by the area code and exchange. So if it was a Ohio Bell Telephone then you look up the area code and exchange and apply the list by the nearest big city on the list. It has nothing to do with state,it is the LEC foot print. The investment in the blanks has already exceeded the 16,000.00 mark as since this was printed I had blanks made to cut 21B,10G and 29S which are the same blank as 29A. All these are available on eBay.
