This is the 'Laura' Stirling Engine 'Gamma type', also called "Hot Air Engine", built from a Bengs kit (link below).

Bengs makes this possible as besides providing the raw materials needed, all milled parts and plates are supplied in the kit.
It is a fairly challenging project as tolerances are fairly tight and getting the engine to run can be tricky. Besides other 'common' machine shop tools, this kit may be even completed with a mini-lathe.
The engine runs to a maximum speed of around 560 rpm as measured by a 'Strobe RPM Tachometer' by Feiwen Apps.
