Well that's an Armstrong-Siddeley and based on that assertion all I can find is an auctioneer's description which says it's a 1934 12/6 Doctors' fixed head Coupé.
The auctioneer says it is a Maltby-bodied car but there's no clue in Nick Walker's Coachbuilding book which tells us about Maltby's drophead bodies - but he does list A-S as a make bodied and sold by Maltby
