I just imported a nice Black Country saddle from the UK that has no model, tree, or seat size stamp on the sweat flap - just a serial number. It does have the BC plate and buttons and looks to probably be an older version of the Eden (or maybe a Riley?), so I’m not questioning it’s origin, but I did notice the serial number begins with an X. I know later models made on their hoop tree are designated with an X in the name, but does that apply to the serial numbers as well?
I have sent an email to the company, but have not heard back as of yet.
