I thought I'd mention that I found a hat that seems nearly identical to Granada Holmes's Homburg Hat. It a Borsalino hat and is available from Byrnie Utz Hats in Seattle (just give them a call—they don't have an e-commerce site).
Here is a grimy camera phone image of me trying one on and a few snaps of the interior. It was a few hundred dollars, as I recall, and authentic beaver fur.



My guess is that any original used in the production would have been likely to come from Lock & Co in St James in London (or similar), but those are considerably less accessible, especially for those paying in USD. The ones stocked by Utz appear to be in the identical style and material.
Given the cost and slight wonkiness of the Homburg, I couldn't resist and opted instead for a totally non-screen-accurate (and relative inexpensive Irish-made tweed) deerstalker.
