Ocana definitely rode a Masi... Wink wink, Seriously,
Even with this pic of the day image blown up in Photoshop is not a very good indicator, other images of Ocana show him on a Gemini painted as a Motobecane. This image has just a hint of the extended blade end at the tip. The primary indicators are the head lug side windows and stay & fork ends showing the "sharkstooth" ending. For reference refer to the recently outed frame at auction on ebay, just ended. Wishing that one was just a couple or three cm larger.
Morelon and Trentin also rode on Gemini and C.N.C., but branded as others.
Also some of the images of the time show Ocana on a Speedwell painted as a Motobecane.
