Heater vent door knobs

I know this is a minor thing, but I have been unable to find anything so far. The knobs in the attached picture are clearly homemade and the second set of holes tells me it wasn't a particularly accurate attempt. Which brings me to the point, what did those knobs look like? There's a bonus question, in the upper left corner you can see the threads of a rod that opens and closes a valve to send air to the defrosters, also short any knob, what should be attached to it? Thanks for any direction anyone can provide.

I could help narrow down knobs if you can find the manufacturer of the heater. It does not appear to be a Harrison/GM product. That being said there were numerous other manufacturers in the 30’s - 50’s that built heaters. These vintage heaters usually had Bakelite or plastic knobs which is why they may have been replaced, they deteriorate over time. Chevs of the 40’s has replacement knobs like these, which would be period correct.

The vent you reference again I could narrow down if you know the manufacturer of the heater. Harrison used simple levers in many cases for the defroster settings.

There are many varied styles in knobs and applications.

It will be easier to find GM or Ford reproduction knobs as they are the predominant survivors.

Personally, I would just put a knob on the top left threaded rod and call it good. Sometimes those little fixes make a cool detail.
