Browsing the-saleroom I stumbled upon yet another RAF captains chair. After some enquiries the auctioneer confirmed the presence of some markings underneath and seeing the regular style of leg that conforms to Air Ministry production I popped a bid on and won. happy days! This one has a slightly rougher but more frequently seen impressed AM and crown along with a 1940 date and makers mark. It has some slight damage but is still dry sturdy and retains much of its original dark stain.
