Digitalizing a small loco

I agree: unorthodox methods, but good quality work ...

Wayne, yes. Absolutely my point of view.

It is rather unusual that the bearing springs were left in place, but it was probably the easiest way to level the drivers. I'd guess that he must have used the bottom cover plate partially tightened down to equalise the spring pressure while the epoxy set. This would fix all the wheels at the same height. It seems like very precisely-done work.

Yes, you are right again. This was also my thought after sending last reply. A really good idea!

And a third time, yes you are right. Rivarossi used such similarly pickup bolts on their models which are mounted inside of frame. All wheels were made from plastic and so they needed pickup feeders on the wheel rims, one side only. The other pole came from tender also.
