How large is Wyvern next to the SLs?

This is not the same method as the IP Eng (holed disk & plain steel), Dream Steam & PPS plain steel wheels which all use bearings which fit into those chassis holes and are held in place by large nuts.

Actually, the spoke wheels had the Mamod style bearings even in the PPS days, here you go thanks to the way-back machine:

Thanks Garrett. Here are some better sized photos.

Strange that the plain steel wheels had the modified bearings (possibly old IP Eng stock?). Wonder why he went back to the Mamod style bearings? Probably customer feedback that those modified bearings take a lot more time to get aligned properly for free running.

And I see the rust has already started on those plain steel wheels!!

Bet the plain steel one would fit well. I like to drill holes in them to make them look better..Have a great break and rest one and all.
