I'll bet you could find one cheap if you looked hard enough.

The old IBM key to card punches that I have seen (and scrapped) were
the model 19 and the model 29. They were small steel desks full of
mechanical and electrical parts that no one wanted, so they were
scrapped for the steel frames and made into small work benches.

I have never seen the punching fixture, but think it consists of a
number of punches with a plate and die that matches the plates in the
tester. Punches are added or removed, depending upon whether a hole
is to be punched in a certain location. When all punches are in place
the (guessing) lever is pulled and a cam drives the punches through
the card into the die. Even this method is pretty darn slow. You
would be working for a long time to make up a set of thousands of
cards. Now there was a guy selling some cards on Ebay a year or so
back--he was in California. I don't know if he has any cards left.

better make that a model "026", and "029". There was also a model "129".

the 026 and 029 were distinguishable by the _round_ keys that stuck up from
the keyboard, like a forest of dowels. The "129" had a contemporary-looking
keyboard. with a grid of square keys.

mechanical and electrical parts that no one wanted, so they were
scrapped for the steel frames and made into small work benches.


I don't know anything about the cardmatic, but if it uses a 'standard'
Hollerith-style punch-card format 'card', then I know where _lots_
of "surplus" card-maker devices would be available. _Everywhere_ that
governments used "punch-card *VOTING*MACHINES*". You could even make up
a 'ballot form' that had a crib-sheet on it for what each hole in the
card meant. grin
