I'd like to get my hands on an old VRA (volts, resistance, amps) meter, similar to the one shown in the early workshop manuals:

I can meaure volts with my Jaycar-special voltmeter, but struggle to measure heavy DC amps. I'd also like the resistor setup to play with generators.
Any old autosparkies got an old VRA (dead or alive) they would part with?
Cheers,
Harv
