18:09 interesting for a transistor tester, that the schematic component table doesn't actually show a transistor, but has every other component, including a valve.

ha ha yes.. and how about figure 1 theory of opperation, show a valve WTF... that is a bit crasy.. and first on next page figure 2 we see the new wounder of the world : the transistor

Looks like it was assembled by somebody who did industrial panels, with all the right angles that are in the wires and components.

The wires from the battery to the device are actually corroded. Replace the wires and clean the switches and contacts

I guess it was ready assembled by Heathkit, because one doesn't normally see a serial number on build-it-yourself stuff.

this is a heathkit serial number sticker, they where in the parts bag :-) i think it is a fun detail to add.
