1 for every year of Morgan Motor Company's history.
They were build for the Centenary.
11 went to the USA
20 (approximately) were made in RHD
The rest were LHD - circa 69.
2 of the RHD ones have been written off (there may be others I do not know of) and as Graham said, Hammond wrote about his accident(s) in Top Gear (I believe he had a few but one was larger than the others).
