i picked up a twin stromberg Waggot manifold from a swap meet about a year ao. im putting it on my just rebuilt 138 grey motor. i was wondering if anyone could give me any information onit e.g value, numbers made, availibility of parts for it. since parts are scarce ( i think) i have had to modify the throttle linkage from a twin carby red manifold. Any info would be much appericated.
