Manufacturer: Etablissements B.C.R.
2 rue Etienne-Dolet
Raynal et Berteletto (1923)
Raynal's motorcycles were among the first to use rear suspension. He was also manufacturer of Poinard* machines. Many models had 98cc or 174cc two stroke engines, others were fitted with sv and ohv JAP engines of 248cc, 348cc and 498cc.
B.C.R. were possibly the initials Bashir, Collin and Raynal or, more likely, B. Collin (the engine manufacturer) and Raynal.
1923 250cc & 350cc models, with Belgian Victory swinging arm rear suspension powered by Bashir and Collin engines.
1925 - 125cc, 250cc & 350cc models. The 250 is a single-speed belt drive machine.
1926 - Belt drive models with JAP fourstrokes and Bashir and Collin two-stroke engines.
1927 - Models fitted with rear suspension of a different design and manufacture.
1929 - BCR was taken over by the sidecar manufacturer Poinard. There is no further mention of the marque after 1930.

Notes* Some doubt about this. Tragatsch may mean that Poinard built BCR machines briefly after purchasing the company after the stock market crash of 1929.

There was a British marque named Raynal. There appears to be no relationship.
