K R W Key Cutter

[1930 coupe]

I have a K R Wilson key cutter, I also have all the Model A key codes.
After cleaning and calibration ( I do not have a after picture ) it makes perfect model A keys every time. I have the plates for early V8 keys but I do not have any early V8 Key Codes. Where can I find early V8 key codes, or what books have these codes in them. Curtis makes hundreds of code books, which ones have early V8 codes, or does someone have a book for sale.
