I'm not sure exactly what you need. My hobby is woodworking and I use a lot of specialty catalogs to get materials and tools I need. I checked my favorite supplier, Woodworker Supply, and found this in their catalog. It might be what you're looking for. woodworker.com/search.asp?search=Tambour Plug this address into your browser and you'll be at the page that has a tamour lock.
BTW, tambour materials can be had at a number of woodworker websites.
As far as I know, this is the oldest I've ever been.
