Actually Mark, back into the 20's they had the straight stays through 35 I think. I like this Shelby completely stripped like that, you can really see the bike. Pinched seat stays were going on since 25 I think. I would hope Mark that you keep the animal parts, streamers and noisemakers to a minimum on this one bike buddy!
I know you love that stuff....
