Thanks for posting the pics, John.
The real rivet counters among you all will spot some anomalies on this motor...
It came from the estate of Charles Harrison, so its origins are known, and it looks like a motor that he was experimenting with. The powerhead had been run, but only briefly, there was no carbon in the exhausts, so I guess it had been test fired in the factory only. The gearbox, carb and mag were all brand new - eg, no scratches on the throttle slide and so on.
But - it's a Mk II powerhead (post-1958), a Mk II gearbox but with a pointy leading edge instead of the usual chisel form, and a Mk I midsection and clamp bracket assembly - known to be structurally weak.
Any thoughts on the reasons for this appreciated!
The hydro(s) that the motor's owner intends to build will be to a set of drawings he acquired from the same source, which are headed 'British Anzani A & B Hydro'. He's in the boatbuilding business, and hopes to digitise all the ply parts so these can be laser cut and offered as a pre-cut kit. Watch this space!
