My thanks go to Andy Grant in the UK for these photos of his old Coronet. Andy writes:
Seeing your excellent site reminded me of the Coronet I had in the 1970's. You could have any colour as long as it was red. The front end running gear was Standard Triumph. The gearbox was either an Albion three speed or four speed. All three wheels were normal car-sized. I changed mine to the four speed, but must say the selection of gears was very hit-or-miss, being an in-line gate. The performance was surprisingly good for
a 328cc, albeit it would be a struggle on long, steep hills.
Worst problem by far was the appallingly bad soft-top, which did absolutely nothing to hold out rainwater or wind.
I bought the Coronet as my next three-wheeler, after having a Nobel before then.
It had a small single cylinder Sachs engine, I believe around 200cc, driving a single rear wheel. It was like a stretched bubble car, with conventional doors at the side. It had a Siba dyna-start, using a variant ignition setting to reverse-run the two stroke engine, eliminating the need for a separate reverse gear (quite a party piece, to change up through the gears as you went backwards!).
I have dug out a couple of slides (attached) unfortunately now very faded, which show the car. The abomination on the top was a home built hardtop that came with the car. It did at least keep even the worst weather out when I used the car, which was my daily transport to and from college at that time. The original soft top had a wooden front bar which engaged into two studs on the top of the screen surround and tightened with
a thumbscrew. The wind would just drive rain up the screen and under the bar, straight into the car and onto the occupants.
The car was chain driven and had fairly good luggage accommodation in the rear, in compartments on either side of the engine. One side housed the spare wheel. The seat was a bench seat and controls were fairly car-like, with the exception of the gear lever. This was
configured with reverse at the front, a joggle in the gate, then neutral, first, another joggle then second, third and fourth, all in a straight line. As you can imagine this required a degree of concentration and some accuracy when changing gear. A strip heater efficiently demisted the screen, even in the coldest weather, there being no other driving compartment heating whatsoever. The dashboard was a sort of woodgrain with alloy trim.
It did turn heads, but I suspect it was more a case of "what on earth was that" or "where's the wheels on the back gone".
