3 numbers all match for a true origianl

[thepennyarcade]

I have a Buckley Criss Cross 10ct slot machine and I can match all 3 number locations.
One is stamped in the base plate, one is written on the cabinet label and the third is stamped into the wooden cabinet .
Do Mills or Jennings slot machines have this same 3 number match up for all original machines?
Thanks
John
