Instead of trying to determine if your wheels are RH5... see if they are something else. True the RH5 is hard to see how it actually works or fits together but all the other wheels are real easy to see how they work
https://www.stovebolt.com/techtips/wheels/images/49_budd_catalog.jpgNotice in the picture all the non RH5 wheels have relatively small removable side rings sometimes with locking rings, and they're always at the edge of the wheel.
The RH5 are the only wheel split in about the middle, both parts of the wheel are almost same size. Or notice the very outsides of the RH5 rim are plain and simple.
If the wheel in question resembles anything other than the RH5 it's not an RH5.
Your wheels pictured are not RH5 wheels, again look at the removable side ring and split lock ring as seen on a front wheel from outside.
