GA to you. I find it funny that you were the first one to get it right - I think you're right, but you only got one GA!

Anyway, congrats on your second GA!

Did you know that's the name of the device on the top of an electric train (that brings power to the train from the overhead wires)? I sat on the board for Metro here in LA County and we discussed the Gold Line that runs from East LA to Azusa - it has overhead wires.

It's a drawing copier/enlarger. I had a "toy" one as a kid, in plastic. You trace the stylus over the original, and the pen on the other side draws it on a new piece of paper. The setting of the various arms change the pivot points and allow enlargement or reduction of the drawing. (That one looks like a 1:1 only, on second thoughts)

Definitely a pantograph. The research machine shop I apprenticed in had several different varieties of them, mostly used for engraving or transcribing sketches or planar objects to different scales.

A pantograph, I believe. I have used them in the past to scale x ray defects in castings.
