Thanks for the effort Nathan.
Are you interested in selling any of those key blanks?
If so, PM me and give details. I live in Toronto, Canada.
I am not in a position to make new keys for these locks yet as I'm only starting to get a handle on the technique of how to impression keys and I wouldn't want to ruin hard to come by key blanks.
I have read a lot and watched a number of videos but have only tried it a couple of times. I'm waiting for key blanks for a few Master Locks that I have and them will try on more advanced and more difficult locks.
