I believe I have seen these on kierin bikes as well as on some italian track bikes. I think i've seen one on a guerciotti too. anyone know where these are sold?

no one? hmm. i guess my next plan is oval the blades for the top 4" or so. my plan is to take 6" of 4x4" hardwood and bore a 1" hole down the center, then split down the center. Then put in a hydralic press and smoosh it oval. I can only guess that this is how some oval / round tubes are formed. I imagine this is done before the blades are raked, which is opposite in my case. once again i will blunder my way thru it...

There's a Cinelli track fork crown for 22mm round blades on eBay:

I ran across this on the Long Shen site and remembered you asking about one.
It's 23mm round (not 24mm), and I think they may have another round leg sloping crown.

U can do that thing with the wood but i would use a vise. It works because i have see it with my own eyes. U can get 24 mms oval / round at the ends fork blades anyways.
