I have a small user manual for the 029 (predecessor to the 129) from the
university computing centre from my keypunch days. It's not an IBM manual,
but it covers basic ops, the front panel switches, and details of the
"program unit/drum" control card, if of any help.

(Did you get lots of blank cards with it?)

A google search turns up an outfit still (apparently) providing maintenance
contracts for unit-record equipment (?!):
