Non-ambidextrous printing frame

Guess the seller is pretty much set in his ways for using this frame

Sorry could not resist.

I have that frame, except that the corners on mine are mitred. Any idea who, aside from someone who knew his left from his right, made these printing frames?

Gosh, like Cole Weston, Edward Weston and the fellow selling the Premier printing frame, I must be pretty stupid for labeling the top and bottom of my frames. I'm so dumb I have rulers taped to the front so I don't guess when I need to hold my cards to burn and dodge. There is nothing creative in the mechanical acts of photography.
