<There is a metal can on the back of the chassis that has a bit of rust on
<the outside, but peeking inside it looks like it is on the the transformer

Rust is not a factor unless loose bits of it are in the circuts.

<fortunately. As for the kind of cheapie it is, I have no idea... it's a
<rebadged Heathkit sold as a "Bell & Howell Schooles Oscilloscope model
<10D-4540".

I'll bet it's a cheapie recurrent sweep design. if so the H sweep should
have a switch that is marked internal/external... you want internal. There
should be a sweep rate switch as well.

lack of vertical deflection is either input set wrong, wrong gain setting
or possible a input selector switch set for grounded(to zero the input).

Heath would be a source for a manual in good likelyhood.
