I have commented on the close similarity between circa 1928 Standard models and the (Wolverhampton) HRDs in the past. As someone who measured up frames to rebuild my own I know the details off by heart! Actually most of the HRD-like Standards are slightly different, with a built-in sidecar lug at the rear frame, and I believe often a hump bent into the top tube to clear the tall MAG engines. Rumours have said it was a licensed copy, but I have never seen any evidence of that. George Spence used to reckon that Ernie Humphries may have been behind it, either with a 'license' (formal or informal), or by selling some of the bikes/spares when he acquired HRD. Not all of them though, because Phil Vincent acquired a job lot of lugs, and a frame jig (see his and PEIs autobiagraphies). Indeed the pre-A and series A rear fork lugs are the same as the 'real' HRD (except with the bottom 'torque tube' attachment points removed.
However I will be interested in any real information that surfaces.
