OMG!

My very first scope was a 502 Dual beam scope JUST like that one!

Mine wasn't nearly so pretty. It was kind of banged up and had a hard life, but it worked just fine. The calibration wasn't even too bad once it had warmed up for an hour...

I paid $20 for it, very used at Mike Quinn Electronics back in about 1975-76.

The dual beam CRT is a neat thing. It's got 2 electron guns and it can display both traces without any need to "alternate" or "chop".

Yours is in beautiful condition!
