Locomotief that is pre Campagnolo brake era. In the 50s Weinmann was used in TdF, but in the 70s you did not opt for Weinmann on your high end racer normally. The component selection of Shimano 600 with Weinmanns is what I would expect on a Cove RIH in the 1st place and not really on a proper RIH.

"Many people draw the line in 72 and beyond that a true rih where no longer being made." I have never heard of that. On the Q on whether any proper competition aimed RIHs left the Amsterdam shop after 1972 I can say yes. Below an example. RIH even supplied track frames to the Dutch national team. I owned one. Cove acquired the rights on the brand including heritage and everything that could help market their Limburg made bikes. The original RIH shop is still Van der Kaaij's. Vd Kaaij simply continued building proper RIHs under the RIH name. Recently there has been a legal fight about the RIH name. Cove claimed Vd Kaaij should stop using the name. I think Cove RIH fear a possible new owner could start bizz that is not in the interest of Cove RIH in case Vd Kaaij sells. Vd Kaaij is not the youngest anymore.

Of course in my view there is only one reall RIH. RIH in Amsterdam that built and still builds fine bikes that were raced to many victories. Not the Limburg Cove branch that adopted the RIH name for marketing purposes.
