T-Bar handle ID

[skrilla]

I acquired these heavy duty handles from a bulk purchase. They say T-Bar on them as well as have an Area Rule Enginering logo on the front. Feels like stainless steel. Welded studs for the knobs. Rubber coated handles. Seems like no way to take them apart to service. Would like to try and identify them and see what reels they fit. Here are some measurements I took with my calipers.

Handle 1:

0.440"/11.18mm gap between the straight edges
0.500"/12.70mm gap between the curved edges

Handles 2 & 3:

0.340"/8.64mm gap between the straight edges
0.400"/10.16mm gap between the curved edges

Any ideas? Thanks in advance.
