Thanks for the pointer, John.
It's a 2465A, actually. In quite good nick, too. I also bought a
classic 475 that looks like it's done very little work as well
(although the trace is a shade noisy but I've come across a web page
that details how to fix that problem).
Plus I *also* bought a 3rd scope which I might post a picture of *if*
I'm feeling resilient enough to absorb all the abuse I'll get from
having acquired such a noteworthy specimen. ;-)
