No one has made a factory red logo in 30 years or so AFAIK. Fender only used the traditional logo on their Sunn branded gear I think, but you might be able to order one of those from them.
Also I believe that bootlegs of the original logo have been produced and sold online, but no one has copied the red logos.
As I mentioned in one of your many other threads looking for a logo, eBay is probably your best bet.
