I got in touch with Richard the Shoehealer about the possibility of Mr. Alfred recreating these desert chukka boots. He contacted them, and although it's not a style they currently offer, they would indeed be willing to do it as a GMTO. If anyone is interested, I'm proposing we simply recreate it thusly:
Alfred Sargent for Ralph Lauren
Style name: Holburn
Unlined suede (either snuff or mid-brown)
Natural crepe sole
Antique storm welt
Price would be approx. £340 inc. VAT,...
