Super Rare Webco Rocker Oil Manifold Find

As lined out in my previous POST on finned rocker oil manifolds for Triumph twins I identified this one from 1960 as what I believed to be the earliest type made by Webco.

Well, a new never before seen example in my 20+ years of looking was found at the recent Clubman's swap meet. The five fin pre-unit manifold. Slightly bigger than the four fin counterpart and drilled all the way through with a set screw blanking the oil hole on the far side. Spacing of rocker spindle holes are an exact match. Year of first manufacture UNKNOWN. One of many exciting finds that day!
