One of the Jungmeisters from the Marcus Bates collection went to France where Bernard Charbonnel of the Breitling Jet Team is restoring it. (Bernard also owns the Jungmann that previously belonged to Alex Whitmore.) Bernard said:

I'm doing on it a full overhaul. The wings are almost ready to be covered. The fuselage is also almost ready for fabric. I fitted a brand new Bü 133 tail built in Spain by Gonzalo Figuera (This email address is being protected from spambots. You need JavaScript enabled to view it.). Originally, my Jungmeister was fitted with Jungmann tail. The luggage compartment is being re-built as original in wood. Instrument panel is complete.  Engine is overhauled again and ready ( Warner 185HP ) .

Regarding the Jungmeister : after investigations and talking with a Spanish historian, Jesus Ballester and Josef Griener,  it seems 99% that it is the 13th Jungmeister of the 25 built in the Cadiz CASA factory in June 1942  I'm waiting more documentation from Spain but now I'm convince of that!
