Bought new (rhd) by a guy called Blenkinsop in 34 and stored in a barn in 1960 when he couldn't get tyres for it! Sold at auction 4 years ago to me! All original interior, paint, chrome (or lack of) etc. Overhauled mechanics and new tyres.
There where 7 Buicks imported new to Britain in 1934, of which 2 are 91's. The other car survives in Scotland http://www.oceanwheels.co.uk/new_site/index.php/Wedding-Luxury-on-your-Wedding-Day.html
He has the original engine but is running it with a Rover V8 at the moment. There is also a 33 or 34 Buick Hearse in a scrapyard somewhere in the UK.
I have the original spare wheel covers but unfortunately they don't fit over the 750x16 tyres I have, think I need 650x16's for the spares.
