A couple turned up in the early 1980s (G-AMLK and G-BISU) operated by Instone, and then headed west to Canada. One returned to the UK in 1996, but was sadly written off in a landing accident at Enstone in Juily that year (the wreck is still there?) and the other crashed in Canada.

Don't think any are currently airworthy and the only potential flyer is in Australia or New Zealand.
