Bruce Tharpe has an interesting story on the Morrisey Bravo having worked for Morrisey before Sig Mfg. He also varified that only one real Bravo was made. Click on his web site, attached. Also, do a search for Morrisey Bravo using "google' and a lot of info on the model comes up.
PS: found that the original Bravo owned by Hazel Hester is not at the EAA museum but at the Airpower Museum in Blacksburg, Iowa
