My recent acquisition of this sort was a 360/5.5 Tele-Arton in a Copal 3 shutter for $425, and it's in outstanding condition. I mounted it on a Wista extension lensboard for my Linhof 4x5", and eventually I'll probably have it cammed. The first couple of test negs look good.

The price penciled in on the bottom of the box (probably the used price, probably Canadian dollars)--$2581.00.
