I have been on holiday and been away from the site for a bit, but just saw this.
I have met Lucas, he is a nice guy probably about my age. I don't know for certain, but I believe he worked for Alaska Bush wheels for a while and now works for Berringer (swiss maker of aviation wheels and brakes). He purchased a jaars helio, 1442 I think, and that is how I met him.
I do believe he is related to the banking family you mentioned, but again I do no know for sure. Only met him once but he was quite friendly and a nice guy.
That is the snippet I know about him. Nothing about the type cert.
