I bought a circa 1980 or 1981 Lotus Grand Prix mixte off CL yesterday. I may enter it into the clunker challenge, so won't post the whole thing here.
I noticed that the front center pull brakes are Shimano "Tourney" and there is a metal arm which acts as the drive side straddle arm. On the back side is a flat metal tab which activates a quick release. I've included photos. I don't see any date codes yet, but once I take it apart for maintenance I will look.
What can you tell me about these? I've never seen them before and I like how they work. Very elegant and clever. Anyone know what year they might be?

EDIT: I did see some photos of these on this side and a few others. I understand they're likely early '80's "sport" model type. I just think they're interesting. Wondering how many of you see these often? How they perform, etc.
