http://www.flickr.com/photos/88104625@N07/8057573424/ Have a look at these and tell me what you make of them.It is very old.I have owned it for at least 35 years and it was old when I bought it.I have tried the ctc,yacf and cycle-chat forums for info.I have now discovered yourselves,I've spent a good bit of Xmas day using the search here to look up all the relevant threads I can find.The serial no reads 9103937 the only original bits bar f&f are the bars and stem .The rest is all stuff from the late 70's, 80's when I renovated it after I bought it.I have not used it for years ,my big bro had it on permanent loan,but now I have it back I'd be keen to refurbish it but I would like to know it's age .I've been to nkilgariff's site but i am still unsure of the serial no method of dates.help would be appreciated.
