This would confirm that my 1982 RC is in fact #842. Built in early Spring 1982 it is possible that the year ended with close to #1100. He built about 5-7 bikes a week--correct me here if I am wrong. So, it is quite possible it could put "maisspecial" bike in either 1980 or 1981. However, I recall all our bikes at the shop in 1981 had braze-on cable guides and braze-on derailleur guides under the BB but that was a long time ago.

Some other distinguishing things about my bike is the letter "C" cutout in lug connecting top tube with head tube. Also, the inside of lugs at the fork head going down the fork has a spade, clover, heart and diamond cutout. Does anyone else have a bike like this? Hope this info helps others put a date on their RC.

Will look for the photos I have of these features and also some photos of Ron holding my bike frame in 1982 at his shop in Honor Oak Park. I think Ron is about 80 years old now.
