Yes, I'm sure Pete is right.But what is it, exactly? It can't be the actual shutter itself. Does the drum shutter go inside? We used to call them barrel shutters. Really, a low number like 9 of any projector is interesting...!

First off, how many Westrex 7000's made it ot the US? Were they ever made there? I'm just curious, as it was quite a popular machine here, but I've never heard any mention of it from the other side of the pond.As far as I'm aware a 7000A with serial number 9 is, well the 9th model A built! Model A was, I think, the coding for the version with the transverse motor, as detailed above. There were other minor differences, that a wise man once told me about, but I've forgotten them now ( I don't recall that wise man saying anything about shutter cooling, other than they added the electric fan on the top of the shutter housing. A lot of 7000 machines were sold with the ORCON lamphouses, which had a di-chroic heat filter in the front. The shutter distortion would probably have become a problem when they were used with xenon conversions (Peerless Magnarc, AEI etc) and larger lamps. Later today I will be working with another wise man who is probably the UK's expert on the 7000, questions will be asked! Neil, if you've only just found that damage, it's probably been like that for years, so I wouldn't worry about it. But like I said, you have a spare machine, so change the shutter if you're concerned.
