Each end has a flat press, sheathed in metal (spot-welded joint) with a stranded-wire lead emerging from lower outside corner. C-8 tungsten filament with eleven disc-style supports (probably tantalum). The ends of the leads are threaded and the filament is screwed onto the leads. Tipless, T-shape quartz envelope.
