Is the magnets with the groove possibly by Hitachi?
These along with the clip look very much like the magnets as found in the Rikochet motor sold by Riko in the UK and by others around the world, including Russkit me thinks.
Fitting these into a Mabuchi motors with rewound armatures was quite a common thing to do back in the late 60's in the UK, they do feel more clunky than the Mabuchi mags but not sure if there was that much of a gain though!

Hi John,
Those magnets (Tradeship? Hitachi?) are definitely thicker than the stock Mabuchis so they result in a tighter airgap without shimming so I guess that's something. After zapping them, they seem only a little stronger than the Mabuchis. Overall, they are a step up from the Mabuchis, but not by a whole lot. These can-in-a-can setups are much stronger still, but the design is pretty fidgety so on balance I'm not so sure it's that much better than just putting modern D can magnets in there because those fit very nicely. Tradeoffs either way. I don't know the definitive answer to your question, but it has always been common practice for manufacturers to rebrand others' products, so it wouldn't surprise me if that were the case.
