CG on Panache
 

Bought a unfinished pattern plane called a Panache at a swapmeet last year. I finished it a few weeks ago and have no idea whera the cg should be. Can anyone tell me where a starting point to balance it at would be[sm=cry_smile.gif]. The plane looks nice and sure don't want to guess at the cg and loose it on the first flight. Is this old enougt to be a classic pattern plane?
