Every once in a while something really interesting pops up on ebay. Here's one of those somethings:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1238810428 As someone else pointed out on another forum, this projector has no sound capability. Does anyone know what this sort of projector would be used for? The entire projector is blimped, which would lead one to believe that it was intended for use on a shooting set.
At any rate, that's a heck of a piece of hardware!

Did you note the Samuel Goldwyn Studios stencil on the machine? This was used for rear projection scenes...hence the high quality intermittant and extremely stable image.

Probably a pin-registered movement (projectors don't get any steadier than that!), taking film with Bell&Howell (BH) perforations. Likely that projector was used on quite a few classic films to project the "background plates".------------------

Don't these machines use the same movement as Mitchell cameras? If so, it's definitely pin-registered and definitely designed for BH-perf film.

The movements in these are quite a bit different than a camera type movement. The aperature is placed far above the reg pins and claw to stay cool, plus the pins and claw are ground for positive perforations, not negative perfs as in a camera.
Bill Hansard has a warehouse full of these projectors in L.A. that contains a number of these plus several Vistavision and hand built MGM process projectors from the 20's. All are still usable and some have been retrofitted with 10K xenon lamps. When I worked on Uncle Buck Bill sent in one of his projectors for rear screen stuff. It has a single blade shutter that syncs with the camera shutter. Ya can't watch it too long unless you want a heck of a headache. Unfortunately these projectors as neato as they are, are mainly relagated to the scrap heap these days. They are rarely used except for special purposes. Stuff is all digital these days. I have pictures of Hansards projectors that I'll send into Brad to post. They are quite unique.

How was the synchronization accomplished between the camera and the projector? Did they just use synchronous motors? Geez, that thing is a beaut.

They used a 3 phase sync motor and a selsyn to the camera
