0717 is july 17th

need casting date off the block to determine year

is is on top ledge somewhere same as how the block casting raised numbers code is

last number is the the last digit of the year it was cast in

for example A129 will be jan 12 '59 '69 or '79 or '89, see

and i know that it is a 70-up block because it has a TKT three digit suffix stamping code

anything '69 older was only two digit such as the other person in this thead's FC code
