Hi, this is my first ever post. I recently bought this Falcon in a shop in Rotterdam but apparently it was originally sold in Ipswich. It is certainly no lightweight at more than 15kg, having steel Rigida wheels and no Reyolds tubing. However it is in almost perfect original state and reminds me of a Falcon bike I bought new in 1980. Even the tyres with Falcon name-stamp seem to be original. There is a very nice working dynamo set, although I'm sure that's not original. Does anyone have any idea exactly how old this bike is? How might I find out? Some details: frame number M8J18427 , Shimano Tourney centre-pull brakes, Shimano Thunderbird II front derailleur, Shimano Eagle II rear derailleur. The head badge is different from the two other Falcons I have owned (see photo).
