I'm not sure if there's a direct connection, Alan, although I'm quite open to being contradicted with the evidence! Williamson's 712S-DFV (S for sprint?) - aka the Marlyn - was built for him by Lyncar Engineering, whereas the 721G was built by March themselves - initially as a one-off to an order from Clarke-Mordaunt-Guthrie for Mike Beuttler to drive - and they later built more for their own use after the works 721 and 721X had proved to be - not putting too fine a point on it - dogs.
Searching Google for Williamson + Marlyn will bring up a number of hillclimb results between 1972 and 1974. IIRC Sir Nick then bought one of the March 741s.
The 'March-Hart' reference is obviously wrong, since the first actual Hart-badged engine was built for F2 in 1976. Presumably Sir Nick entrusted the care of his DFV to Brian Hart's establishment, which was at the time better known for tuning FVAs and BDAs. Brian was of course ex-Cosworth.
