Which Type of Tambour for '70 Sov. replacement?

[Rege]

I have two tambour roll-up upper storage cabinet doors that are in terrible shape, the others are fantastic. I'd like to buy a roll of tambour and redo them myself. (Thanks for the instructions

I followed a couple links from other threads, but I don't even know what kind of tambour I have or what the finish might be. How can I tell what I need to order? I'm guessing it's wood veneer, but I want to be 100% on a match before I order.

Any advice on how to match or best prices on suppliers?

Thanks!
