Finally i have been able to buy the rih that was subject of this topic.
Included are some pix where my main q'n is was this frame made by v/d kaaij in amsterdam.
Other than that i'm very happy with my rih despite possibly being a cove example.
Yes, it's a RIH made by Cové. The serial number's location and type gives it away. The Bocama long-points and the components are typical for a Venlo RIH and your's isn't the only one with a renewed headset (you could change it for an 600EX headset, they're around for a dime).
But seriously - why do you think it's worse than an Amsterdam bike? It just hasn't got the panache - but you can't ride panache. As far as I know the Cové bikes have a much more relaxed geometry and that's why they should be more comfortable on longer rides than the twitchier Amsterdam bikes. But they're both made of the same stuff, 11 tubes Reynolds 531 (you might remember that the tubing is among the best you can get), while later Cové bikes just had the 3 main tubes 531.
And your's has got a
very pretty color scheme.
Ride it and be happy. The ride as well as the people's reaction to your bike will tell you that you did well.
BTW - those guy knew what they did when the left out the Shimano brakes. The Weinmann 605's I have are among the best vintage sidepulls I have ever used,
lightyears ahead of 600 EX and a quite a bit better than Campagnolo Record. Keep 'em!
