Weinmann seems to have a few variations of levers for their Vainqueur brakesets throughout the years. I am not familiar with these brakes and could not find a good answer in the archives. The version I see most often is this, with the quick releases and the textured "dots" all down the lever body:

Then there are these, which are the same except that they appear to have been milled:

Does this milling denote anything as far as time period? Are there any other ways to pinpoint the date of a Weinmann brake lever? Or perhaps the design remained relatively unchanged?
To be more precise, the period of the bike I am looking to put Weinmann levers on is early 1970s. If anyone has suggestions on what to look out for, please let me know.
