On the plus side your saddle is a rare beast, I remember reading somewhere about a fabled 7-rivet B17... also it has the biggest rivets which is not normal.
Either a custom job or one of the rare collectors' items.
Sweet, thanks for the info! I'm afraid Bristol is not an option since the frame (and I) are located in Germany. I wrote an eMail to Krabo (Krautscheid) in Bochum, they build steel frames since 40 years so I figure they have plenty of expertise...
Shit.

Take the frame to the best: Argos in Bristol.
