It's not the job sequence number in block 1, 8574, but rather the SCHED NO DATE in block 10, 9 92-66, that I find odd. I've never seen anything like 92-66 there before. On all those I have, if the first number (9) is less than 2-digits it's padded with a zero such as 09. In the second set I've never seen a number larger than 12 to the left of the dash character nor larger than 30 to the right of the dash.
A couple of other things don't look right...block 34 is blank (odd for a big block car) and battery is listed as R79 - I thought the H.D. battery was R79W?
