Vegantune Slide Throttle Manifold with cam driven assemblies and several sprocket options. Port spacing matches typical twin DCOE manifolds. Two cast alloy cam driven brackets; one appears to have been modified for clearance. Missing one trumpet assembly. Has been on a shelf for over 30 years, no known history. LIkely was mounted on a motor used in a Lotus 23B. Looks to be the type used by Alan Mann prepared cars.
