Chris sent me this picture a few weeks ago now of his wife's and his bike on a day trip in Ireland. As you can see Susan's bike is one of the early twin lateral Miss Mercian frames. This is a couple of there large collection of Mercian frame's/bikes. His email is below :-
This is two of our Mercian's at Dunluce Castle in Co Antrim were we call often as a friend of ours owns a small cafe called the " Wee Cottage " where all the food is home made. Cyclists are very welcome here and if any of your customers are touring in Ireland tell them to call. If anyone comes into the shop and needs advice about cycling in N.I. they are welcome to e mail me.

Thank you Chris and Susan for the picture and email.
