Butterfield Musketeer prototype snapped

While reading about the Tornado Talisman recently I came across some cool pictures of the car in its prototype stage at Williams & Pritchard's workshop in Edmonton, London in 1961. But hang on, what was behind it? Yep, there's no doubt about that being the Butterfield Musketeer prototype in similar build stage, too! It fits in with what Richard Butterfield told me about 10 years ago as he'd trusted the job of body-bulding to them. W&P had previously made the much-modified body for Richard's Triumph TR3 and were now given the job to make the two-seater coupe body for the Musketeer in aluminium. Richard remembered it was finished just in time to have the car assembled for the Racing Car Show of January 1962 - the same show at which the Tornado Talisman made its debut... I found the photos were on the web also, and copied them here.

What happened to the prototype Musketeer remains a mystery to this day. What we know is that the original car was put on display at the Racing Car show in 1962 with a Mini 850 engine. Later that year, it was used to plug a mould to make replica bodies in fibreglass, while at the end of 1962 the car was rebuilt with a Cooper engine. It was then entered for the Peco Trophy race at Brands Hatch with Christabel Carlisle behind the wheel. She spun it and did not finish, but after that every trace ends. Any more information would be highly appreciated.
