OK sorry. Is it ok to talk about serial #s on the internet? I guess a person could get any old titanium frame and with the info obtained about serial #s, they could conceivably try to pass off their titanium frame as a Spectrum. Not trying to thwart your efforts of getting the info you need, but I do hope you are able to get this info. Anyway, why is it so important to know serial # information? And in the 1st place, why don't you just contact Mr Kellogg or someone else at Specturm?
