Lobb Paris doesn't make any Hermes-branded shoes I've seen. Santoni, I've heard.
As Etienne said (Etienne, forgive me, it's been crazy) Hermes tends to buy its suppliers. When it was selling Lobb Paris in its boutiques, it bought the old EG factory (after taking a stake in EG) to make the shoes in.
Its glover is the Ganterie de St-Junien, which it bought fifteen or 20 years ago and which, in any case, makes some of the best, most luxurious gloves I've ever seen. Although I'm still hunting...
I don't know who makes their shirts; someone said Charvet but the more recent Hermes shirts have been a little too spivvy to imagine being made by them, not to mention I tihnk Charvet's better quality.
I believe Mackintosh made some of their macs.
Bear in mind that these suppliers may be making the products but that Hermes can and often does specify a level of quality of materials and/or make that can surpass what these makers put out on their own. The Hermes umbrellas are quite particular, for one -- I believe they had cotton canopies.
