Tost offer their EASA approved retractor winch for a variety of aircraft
including the Husky A1, A1-A, and A1-B. They also offer the tow
release support alone for some aircraft including A1/A1-A and the A1-B.
It is an approved part of the EASA kit, not certified in itself. It may
be
worth contacting Tost for clarification.

Tost don't offer a kit for the L-19, possibly the USA is the only place
where this ex-military aircraft is used as a tug.
