1981 King of Mercia
I really need to take a better picture. The frame was given to me by Bubba, what a guy.

You do not have to go to the UK for a fitting. You just need a good fitter who can use the numbers from the fitting to pick a production frame or order a custom frame. It isn't any different than ordering a frame from any builder except Mercian happens to be in the UK.
Mercian is an old and great name in steel cycles. They're even working some carbon into the mix. Lugged or fillet brazed. Get on the other cycling forums, such as Serotta, and post if you'd like more recent experience than mine. Mercians get a lot of oohs and aahs from a knowledgeable crowd.
