Yes, Revell has marketed the original Viper in the USA. I have one right now in a Revell box with a copyright date of 2007. I bought it at Hobby Lobby in 2009, in fact this is my second one, I bought one of the same in about 2008 at HL and built it for my son. The second one is for me. HL sticker price in 2009 was $24.95, same as the Mobius version from CultTVMan.
And I agree- the original series was the best! Never got interested in the "new" series.
