I wanted to enter the Avia 57 in that race, but I wasn't sure I would have the time to dedicate to it right now :/Another suggestion for you - there's currently an ongoing race from London to Melbourne going on here, in this forum:

One version of the race, and the one with the greater amount of contestants (myself included), is the version taking place using planes produced prior to 1938. A quick perusal of the entries, along with a read of the official rules (there's a list of allowable planes in the appendix), will turn up many, many, very fine examples of golden age planes of all sorts. I myself have found several gems that I was previously unaware of.
