Graphic Arts Scaling Tool

[Pieter12]

I am trying to find a tool I used to use as a designer, for scaling and cropping photos. It consisted of two L-shaped transparent, bright magenta acrylic pieces connected with a metal bar. I have attached a sketch. An internet search doesn't turn anything up, but maybe I don't know the proper name for this tool. Anyone remember?
