I picked up another seat for my America, swapped some parts I had for this flamed solo saddle. There isn't a manufacturers label or marking underneath, I did put a picture up on the Triumph facebook forum and some said it was a British Customs seat. I like the look but it is noticeably firmer than any of my other seats I have (now a total of 4 seats 2 of which are solo)
A few of my mates have got custom seats made by Stuart from "House Of Custom" in Glasgow (used to be called Area 51) he makes a brilliant job http://www.area51customcycles.co.uk/showcase/seats.html
