There were a couple in Model Engine Builder such as the Vietti which is quite a bit smaller than the Minimag one

EDIT, he has a few engines with mags on his Youtube account, also sometimes posts on HMEM

Consider this an expression of interest should you make any 'out of the way' discoveries..

yes Robert but no mag kits

I bought a Minimag short form kit (FMK) in 2019. At the time they were not in stock, and the comment from them was that they had stopped making them due to lack of demand, but that perhaps they should not have. Anyway, at the time they managed to source some of the necessary components and put together one for me, and I think possibly a few others. So it would be worth contacting them to see what they can do.

I had some fun getting mine timed up properly to get a decent spark, the breakthrough was when I bought an oscilloscope, (not just for this job) which enabled me to see the voltage across the points and so get the timing set accurately. I haven't actually run the engine yet, there are some fiddly bits on the carby that are giving me trouble, but I am confident that the spark will be OK. The Minimag kit is not too much of a challenge from the machining point of view, the timing is a bit tricky since the cam is inside and only accessible though a small hole. The engine is a PM research Red Wing.

I have made a few engines with dummy magnetos which contain a magnet and hall sensor

This let's me make a scale sized and shaped unit that is driven by some small pitched chain
