Do you have photos you can post a link to? My Mercians have the serial # on the bottom of the BB shell, but they are all late 70's/ 80's, so the numbers might have been elsewhere in the 60's. I think it has been generally accepted that lugged steel Mercians are KOF and therefore OnTopic here, even if they are outside the CR timeline.

It is fitted with 700 wheels but may have originaly been built for 27" also fork crown is a 'Wagner' one -flat topped, the transfers are mid 60's onwards,it is original paint etc and is in very fine condition,I have been on Mercians site but cannot match the model.
