The Bolex M8 & M8R are both very well made projectors and are amongst the best Standard 8 projectors ever made. They do however use quite expensive lamps and make quite a bit of noise when running (sounds a little bit like a hair dryer).

The early Bolex M8s have a textured olive green finish, while later models have a smooth grey/silver finish. Some of the later models also have a stroboscope which allows you to set the running speed to exactly 18fps. On both the Bolex M8 & M8R if the projector is running too slowly the motor will stop and start every few seconds to warn you to increase the speed.

Bolex is still in business and I believe that they can still service these projectors.
