I wanted to look up the pinout for the five in-line pins of this

I couldn't get the right search term because I don't really know
the standard way it is usually described.

It's a dual track ("twin track"? "double track"?) pot with 5 pins.

QUESTION 1
What's the usual way to describe this and, if possible, also refer
to the fact it designed to use a thumbwheel?

Thumbwheel volume pot.


QUESTION 2
Is there a standard convention for the pinout of this sort of pot?

Probably not unless it's an Alpha Taiwan copy of an ALPS model ( at a
rough guess). Equipment incorporating such cheap parts isn't intended to
be repaired quite frankly. It's not the 'modern way'.
