Ok so I misspoke earlier. This Hicks and Sons is not Savile Row. It is Sackville Street which is 1/2 block from Saville Row. So I was pretty close...globally speaking.
3 Button, Ticket Pocket, Lapel Button Thread, Surgeon Cuffs, Double Vent. About a 40S...see measurements.
Hicks & Sons used to have an address on Saville Row - at least sometime around the 40's and early 50's.
I know this because I once found like 15 suits and smokings from H&S and they all belonged to a Danish consulate, who happened to end up in London because he had went to England on holiday just before the war started (WWII) and he had to stay there for quite some time because he didn't want to return to Denmark, which was occupied by the Germans.
His name was in all the suits and I did a background check on him. He had died a couple of months earlier and there were mentions of him in some of the bigger news papers in Denmark.
I never bought any of the suits. I sort of hoped, that someone would buy them and truly appreciate the old-world tailoring craftsmanship.
