Can some one who has a Kodak Panoram 3A tell me what size film you actually need for it?

There is one for sale here in Sydney that is in great condition, the fellow selling it says it tales 120 film but all the web sites I can find say it takes a larger size.

There are also a couple of 4A (? film) and a 1A (? film) in slightly rougher condition, can anyone confirm the film size they need?

I want to get one of these cameras to try my hand at panorama format but want one that I can get film for (probably JandC) without having to cut it myself as I do not have a dark room yet.

Any advice or information would be very much appreciated.
