I have 4 sets of 450 wheels, each set with matching datecodes: - One set of 4 with 12-11-69 dates - One set of 4 with 9-25-70 dates - A second set of 4 also with 9-25-70 dates - One set of 4 that are hard to read, but I think they are 9-30-70. On all 4 of these wheels they seem to have a line over the top of the '9', very faint but on all 4 wheels.
