HEPU aircraft engine for Tipsy Nipper

[OGHepu]

Hello everyone,

I am currently looking to purchase an original HEPU aircraft engine that was used on or intended for the Tipsy Nipper (1950s / early 1960s).

Condition is flexible – complete engines, cores, or engines in need of restoration are all of interest. Documentation, history, or spare parts related to the engine are also very welcome.

If you have an engine available, know of one, or can point me to a lead, I would greatly appreciate your message.

Thank you very much!
