The spreader bar is connected to the uprights of the frame with

A question:

As a kid, my dad described a one man saw with a frame and a 24"-30" long
blade as a "Buck Saw", used primarily used with a cross buck to cut up
brush from fallen trees.

Had a turn buckle arrangement inside the frame to tension the blade.

Is that the same as what you are describing as a "bowsaw"?

Yes, it's very similar. There are also modern incarnations with steel
frames, mostly sold to cut green timber. The major difference would be in
the cut of the blade, and secondarily in the lightness of the frame.
