I believe they can get 8000cps out of the rebuild (made from original

happen to be visiting the park)

Paper tape readers can go much faster (I've
seen 2000 cps) but those
are optical readers, so the job is far easier.
At this stage I have to jump in with an impressive 5000cps example
(albeit 5bit) from 1944; of course it is:

(This is a nice page on the optical reader)
