There's an auction of a local chap's lifetime collection of old cars nearby, on the 25th April. Amongst all the ancient ironmongery is an interesting little three-wheel electric invalid carriage, which I guess dates from the early 40's. It has tiller steering to a bicycle like front wheel, and the handle itself is rather like a spade handle. Leather seat and pretty solid bodywork, doesn't look as if it needs too much work to re-commission.
The chap I spoke to knows nothing about it, and in the auction brochure it's described as an Auto/Elec Invalid carriage.
The Auctioneers are Stags, 19 Bampton St., Tiverton, 01884 255533. The vehicles are at Greenleas, Station Road, Bow, Crediton EX17 6HU and the official viewing day is 24th April, 10.00 to 16.00.
