John Lobb (London) does not produce or distribute any RTW shoes. Nor do they use their name or sell any product outside the St James shop. I presume that is part of the contract with Hermes when Lobb sold its French branch (and I presume, worldwide exploitation of the name) to Hermes in 1976. According to Flusser, Lobb (Paris) didn't rush to enter the RTW market. They had Edward Green in Northampton making their shoes. Later in 1994 (maybe EG was in financial difficulties) they bought "Westminster Works" the Edward Green factory, renaming it JL (just the letters). JL made John Lobb and Edward Green shoes. In about 1996 did Edward Green leave the factory and set up its own production facilities at their current address "Chelsea Workshop" in Cowper Street, Northampton. I do not know, what happened between the two companies; they are both quite coy when asked and say: "We shared production facilities." Are you sure that your pair of "Williams" is RTW and that it was made in France? Although some of the casual styles are made by Heschung in France, as far as I know, all the dress shoes are made in Northampton. The logo JL, same typeface, back to back, is used by John Lobb (Paris) in their RTW shoes but not by Lobb (London). Also on all their accessories and care products. http://www.johnlobb.com/
To come back to the bespoke JohnLobb (Paris) shoes, do they use the same (Victorian, I presume) signature as John Lobb (London), but without the Royal Warrants? Even more confusing.
