After AC had produced a small number of drop-head 2 Litre cars, an arrangement with Buckland Bodyworks created another open top variant. The AC Buckland featured slightly different styling, with a single piece fold flat windscreen and a hood that folded away out of sight. Just over 70 of these cars were produced, and then AC built a small number of their own (known as 2 Litre Sports Tourers).
A prototype Buckland was built in 1948 on chassis number EL1036. This featured door styling not unlike the Saloons, but with the wing-line continued a bit further along their length. The production Bucklands had the wing-line continued all the way to the rear wings. Some Bucklands had cut-away door tops, and others had straight top doors.
Like the Saloons, a change of side and tail-lights during 1949, meant an alteration in the wings for mounting them, which helps to date cars.
Some Bucklands were campaigned on circuits, taking advantage of the fold flat screen and tonneau cover for reduced air restistance.
Incidentally, a cream coloured Buckland that came up for sale in Portugal, wrongly claimed to be the brochure car and the prototype. The protoype and brochure cars were not even the same body style as each other or of the car for sale!
Alternative body styles appeared, probably as one-offs. Such as partially enclosed rear wheels. A Buckland with head-lamps positioned where the side-lamps usually are, appeared in the British comedy film "Laughter in Paradise" in 1951 (briefly near the beginning, and just momentarily at the end of the film).
Production tapered off in 1952, and AC built a few of their own during 1952-54, as 2 Litre Sports Tourers. They can be distinguished by opening the doors to see the coach-builder's plates. AC appear to have built 16 of these.
