In 1948 ARO introduced this box top work station, that was built off of a Lincoln bench.
They complemented their portable lubrication line, but sadly only lasted a few years.
Sometime after 1950, they changed the side cabinet style to this round, short top, and added on a taller middle section and different marquee. You can see the Lincoln lower bench still being used.
By the mid 50’s the company was no longer putting out their own cabinets, but attaching their badges on Shure workbenches, with added reels underneath.
