I have some friends in France (my wife hails from there) and have asked them to see if they know of anyone selling any PRV manifolds in their clubs. One guy knows someone who has a 1977 Alpine GT manifold with the 2 carb set up. According to Wikipedia, it's this one:

A310 V6 Series 1 1977–1980 2664 cc (R 30 TS) V6
Power 150 hp (110 kW).
1 carburetor single throat Solex 34 TBIA and 1 carburetor double throat Solex 35 CEEI

Any idea what it's worth? He said to make an offer. Also, any idea how much it weighs? Is this steel or aluminium?

Thanks,
