I'd like to say it was all me but when I saw it I was able to "that ain't italian" and maybe it was British but that was it. T-Mar and Bertinjim and scarlson and juvela and unworth1 and a few others recognized it. I contacted the MKM website and gave them the sn 3878 and they confirmed it and confirmed it was built in 1976. Also said that as a plus it was upgraded with fastback seatstays which cost 3 pounds (about $16 US) extra bitd!
