I bought this bike 2 days ago. I searched for some info, but couldn't find it. The only information I found was to be around 1972
Assuming this is an Eddy Merckx, you can tell a lot about it from its serial number, which should be stamped on the underside of the bottom bracket. There are a few serial-number decoders online. Here's one. The one confounding factor is the "CR" seatstay caps. Merckxs usually (but not always) had an "EM" cap. That orange was a popular color for Merckx bikes, but usually there was a blue panel on the downtube, not seat tube, and I don't think they ever were pinstriped.
