Dexter's Camera and Hi Fi on Main St in Ventura has more old camera gear on display than just about anywhere, 4 shelves on at least 30 ft of wall. I don't know how much of it is for sale and how much is the owner's collection. They'll even have a varying selection of darkroom supplies and equipment.

Check out the pic at the top of their website:
