Dear CR list, I was asked by a friend to check with the CR list for an Ideale model 58 style, seat clamp.It is supposedly for the flat aluminum seat rails found on the model 58. The CR website has a picture of a model 90 flat seat rail style Ideale saddle I'm guessing it (the Model 58) is similar to the Model 90 Ideale seat clamp used on the flat aluminum seat rails as pictured on Dale Brown's CR website in the French (France section). Any help would be greatly appreciated. Please contact me off list if you have any information on Ideale saddles. Yours truly, Martin Walsh in Vienna,Va
