You have done justice to a wonderful frame.
I have a few British bikes from that same period, so I can appreciate your perseverance in getting the parts.
If you wanted the cut away saddle, then Rudi could easily do the trim and tie for you.
Are there any other parts on your wish list?
That catalogue page is very tempting.
I have made a mould and recently cast some Shockstop handlebar end plugs for some of my bikes.
