I bought one. I returned it. The "red" bone was more of a pale salmon. The blades on the newer 4-spring versions are really thin and very flexible.
If you're really interested, the model number of the red bone CV 64052 is CA6992, and you can google that. It's discontinued, but maybe you can find one in stock somewhere.
Personally, I'd scour eBay for a vintage 70's one in red bone and hope the bidding doesn't go too crazy.
