Changed the posting, see what this drags up.
You also might check with Oklahoma City aircraft registration. If the plane was ever under US registration there could be a file with the original airworthiness certificate. Bill Bayne might have a record of it's original N number. Post the serial number to the list. Problem is, lots of Coupers at Oshkosh this week.

Since we wil reregister the plane to US registration, and our DAR is reasonable but strict I wanted to have it right and no questions to be asked. Because the plane has been in The Netherlands,out country, since 1947 it wil be difficult enough cause I don't think the original american registration form is stil there wich, wil be very important so to make it up, the aircraft has to be tip top, and also, that's the way I like to work. Just like to do it as it should be and not cutting corners. And just as you are talking about it, do you know someone who might have a 337 for this conversion?
