Bob Fisher manifold.

[RAEME]

image.jpgHi all. I was looking thru a mid 90s hot fours magazine the morning, and found an old advert about Bob Fisher Blower manifolds. There was a real trick looking one that was on a 671 mounted on a small block chev. It had a chamber on top of the manifold and then two swept down carbi mounts on each side. the Carbs sat on each side above the tappet covers. Has any one seen one of these for sale anywhere? Or know how to find if they are still available? I will try and take a photo of the pic and attach here as well. Cheers
