There's almost always one or several on ebay at any given time. I've bought a couple of 55s with no cutters, except maybe one in it. 45, and Record cutters work in them too.

So do 55 Cutters work in a 45. I had been led to believe that they were not interchangeable

I'm sure some of them will, like the beaders and plow cutters. I'm not sure about all them. They both have the notch in the top that engages the cutter depth control.

If I need a particular one, I just buy it individually off ebay.

I checked ebay for you, but none currently worth buying. Make sure you get one with all the parts. Slitting cutters and cams, for example, go for more than it's worth to buy one without these pieces.

Do a Google search for 'Stanley 55 plane manual", and print it out when you find it. It will show all the parts so you know what you are looking at when bidding on one.

I've bought two complete ones (with only one cutter) off ebay for around a hundred bucks, but it takes some looking, and being lucky to bid when no collectors are after it.
