1968 Topps Johnny Bench Rookie, variation or printing flaw error?

[Kevvyg1026]

The 1968 set has 598 cards, so it is identical in size to those issued in 1965 & 1966. The printings of the various sheets for the 1968 series' are slightly different, however.

From some uncut partial sheets I've seen,
a. cards 1-109 are in 1st series (110 cards since check 1 was DP),
b. 110-196 in 2nd series (88 cards with check 2 printed again),
c. 197 to 283 in 3rd series (88 cards with check 3 printed again),
d. 284 to 370 in 4th series (88 cards with check 4 again),
e. 371 to 457 in 5th series (88 cards with check 5 again),
f. 458 to 533 in 6th series (77 cards with check 6 printed again), and
g. 523 to 598 in 7th series (66 cards).

The 6th series has 44 cards printed at a slightly lower frequency than the other 33 cards in the series.

I am attempting to re-create the sheet arrangements for each series. At the moment, I am working on the 3rd series and would appreciate any postings of any 1968 uncut, miscut, or wrong back cards, particularly for the 3rd, 5th, or 7th series. I have enough info for the other series.
