Bob -
There was almost an entire issue of "The Restorer" in the 1980's (?) dedicated to Model A accessories, many exotic ones as you have requested. The issue consisted of contemporary ads for such items, as well as subscribers' Model A's sporting surviving accessories. If one could dig up that issue, it would provide plenty of eye candy for those people interested in Model A accessories.
I also seem to recall an article - perhaps in the same issue - that featured one owner's Model A that sported something like 157 original accessories. Many photos and a list of each accessory accompanied the text. Another issue of "The Restorer" was dedicated to unusual radiator caps, which would be considered accessories, too.
Along these lines, Rainmaker Ron's 1931 slant-windshield Town Sedan had many accessories installed. I believe he posted many photos of the car here. Perhaps a search would bring up those postings?
Anyway, these are pretty good staring points for your quest, Bob. Heck, you probably have all these back issues gathering dust on your library shelves and have forgotten about them!
