Atlas FJQ/2081 end shot minus diffuser

Identified as a Atlas FJQ/2081 dating to around 1952, this highly unusual Atlas fitting was acquired to the collection with help from a fellow collector.

Originally wired for Quickstart BC tubes, at some point in around 1968 it had been crudely regeared with Transtar gear to take bi pin tubes. Whilst in a way I can understand the move, it just seems unnecessary to replace the gear as well, seeing as the lamp holders shown here are simply screw terminals rather than push connectors.

To replace tubes in service, you have to remove both end caps and either slide the diffuser off the fitting, or disconnect the tubes and slide them out the diffuser, a very poor design really, especially if its fitted in an area where space is at a premium. Despite this, I really love the design, its got to be one of the most unusual fittings I've ever seen.

This part of the fitting is perhaps the better thought out part. At both ends of the base are two small channels where you can push the sides on the gear cover in to remove it from the fitting. This means any work needed to the fixture in service is kept tool less unless you need to actually work with the wiring. It also gives better view into how the tubes actually seat in the rings during normal service. Overall its a very simple but effective fitting.
