Grog,

I have a small Carradice bag and I love it. I don't have a Brooks saddle so I purchased their adapter and it works great. I ordered my bag through a shop in the USA so I could avoid any hassles. I wish I could remember who I purchased it from but at the moment it escapes me. I do remember doing a search for Carradice bags and it produces a number of bike shops. I then searched their individual websites for availability of the bag I wanted. Hope you find what you are looking for. Again, they make great bags!
