FK-12 Comet French "17-FK" - help please

Hi

A "new" Comet was seen at Hannut in Belgium in 6.08 - this wears French registration "17-FK" - the Comet is yellow and wears "ULM Oleronais" titles - I have not heard of this FK-12 before.

Who can tell me the construction number ( c/n ) of this aircraft please ?

With thanks to Ken Ede for this report.

UPDATE #1 28.7.08 - ANSWER - I've been told that this aircraft is c/n 57 - Thanks to Christian in France

UPDATE #2 6.10.08 - Thanks to Freddy Ceulemans in Belgium for the news that this FK-12 Comet has now been registered on the Belgian aircraft register as OO-G12
