After a long wait, and paying unexpectedly high fees to the freight clearance company I finally have my hands on my 029 keypunch. To my surprise it has an extra wide punching station which apparently is an extra read head which allows it to be fed with ready-punched cards and the text to be printed at the top of the card. An interesting bonus. It uses the same wire relays which have been discussed here recently, and fortunately I have a 303 ammunition box full of spares including many of these from a verifier I broke up some years ago which I kept for my 836 punch.

The rating plate shows .4kVA which is more than my Flexowriter transformer can handle so I have ordered a modern yellow industrial 110v socket so I can try it on a 3kVA transformer I have for an angle grinder. I have searched though eBay for normal US wall sockets and to my surprise cannot find them. I've tried all sorts of search terms but obviously have not hit the right combination, unless there is some law which prohibits them being sold retail or something like that. Probably me being stupid.
