BD ... this is a compact "C" Press and not an arbor. It is similar to a Harrell's or Bruno BR Press, but I don't think it's either. I could be wrong. As far as who made, not a clue.
The back end mounting plate seems odd, if clamped to a bench, the ram would not be perpendicular to the bench due to the angle of the mounting plate. The only other place I've seen this is with the guys who make their own jacketed bullets, they tilt presses back.......Looks like an off shoot "c" press for loading at the range. The back end would clamp to a bench using a "C" clamp like many group shooters do nowadays. I'd say someone copied the Harrels compact press.
Those flutes are just decorative - I think.the design cut in the arms and side, front, of the press is a clue???
