It is always a subject of discussion. The thread running through every story is: Kessels did not make
frames but imported them from framebuilders. Vaneenooghe in Ruiselede and Gaston Orlans in Gistel, both in West Flanders Belgium were two of the builders.

Eddy Merckx used in different races between 1971 and 1977.

How to identify a Kessels Eddy Merckx frame

I found my 1971 Molteni bike three years ago, in a hedge(!) here in Bruges. When I asked the neighbours for the owner, they told me that it was a student’s bike. A couple of weeks later I managed to buy the bike for 50 Euros. It had been converted to a fixie by the student, and on top of that, nature (the hedge) had also taken its toll.
