Hi
Aries in Etonia used to have one, there are a couple left in Germany too I believe. One is being operated out of Geneva on a N reg(Execujet), also one in I believe Sion( Alpine jets?) if I'm not mistaken. Omni in Portugal have an old 31, and there used to be one opeated by Airlink Airways in Shannon.
It's a beauty to fly, but I think they are about to be extinct in the European marked at least.
Good luck
O
