Atlas FJQ/2081 internals

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.

Seen here with the diffuser and gear cover removed, the internal gear layout is exposed. The whole conversion feels very lashed into place, as wires just hang freely, with nothing to hold them in place to prevent trapping between the base plate and cover. Other than that, its confirmed to be in working order, so thats all that matters really.
