Wow that's pretty cool to find out about the frame. I almost threw my back out lifting this thing which was deceiving for it's smaller size. I'd say it's at least ten pounds of the finest straight gauge British sewage pipe the Queen had to offer.
As for the band around the seattube down by the bb shell. I couldn't really make it out too much since it's just a outline of what used to be there. Now to find some haggered NR parts to get this beast on the road.
