doesn't look like the 742A-14 was jackpot only ... the rest of the payouts would be on the reel glass. Below are the reel tapes.
the tricky thing will be finding index discs. You need P-484-[133, 134, 135] to make a 742A-14, and from my info they are unique to the 742A-14. Other versions of "break the bank" used different index discs.

the index disc definitions and payout counter are below.
