Matt, take a look here:
NAvion N4584K
I'm flying the orange NAvion... all the pictures of other aircraft without 84K are taken from it, All pictures of the red and white one on the Bay Tour are taken by Dr. Bertagnoli from the right seat. The red and white NAvion is a multiple show winner with an IO540 and a bunch of speed mods. It is like a brand new 1948 aircraft.
Cudos on 25W... that's an amazing achievement to build your own plane. How many years? Are you an A&P?
All the best,
Mark
