Looking for Formula Emblems (Cursive text)

Hi!I am searching for the Formula emblem from the 233 70's line, the one with cursive text and a somewhat smaller bird. I am overthinking to strip her down of her stripes and make her a little more elegant. I have found some on ebay but they only make the birds. I would want to know if the cursive text fits mine as well. You can see the emblem and text I am looking for in the picture below. Anyone who have extras or know where you can find them? Thanks!See More

Devoted to the famous 233

This registry is dedicated to preserving the heritage of Don Aronow's famous Formula 233. A place to network with other 233 owners, discuss technical issues, get and give advice, exchange knowledge and compile a database of the remaining 233's. If you've ended up here you've got some connection to a 233. Special thanks to HORBA for providing images. Please visit the Historic Offshore Race Boat Association , an organization dedicated to educating the public about the history of offshore racing. Welcome and thanks for visiting.
