Starnord-Dangre from Valenciennes doesn't exist anymore.Starnord had a professional cycling team around 1950 with blue-red jersey.In the sixties it was a smaller mass producer of bikes mostly sold under department stores or post order brands,its own Le Nordiste brand or branded after cycling heroes like Anquetil or from believable hearsay Merckx in 1975 only.
I have a Jacques Anquetil gaspipe 10speed mixte which is an accaptable entry level sport bike,nothing special today but in its day something to be proud of,much better than the single speed or three speed Sturmey Archer bikes 95% of thepeople rode.
