yes it's quite a story...when i look at the bicycle I assume the paint is original and also the name RIH is not added...paint and letters look really made at the same time.
Most interesting the lugs of the headset are exactly the same (for so far I can see) with the RIH cove. But more interesting these lugs look also more to the lugs they used in
early sixties....while the lugs from RIH fingers and RIH amsterdam from late sixties/early seventies look more simple....

I cannot believe it's not a RIH at all. Also the blue plate at the front looks really original and not added later...hope to hear more from other race bikes fans
