Mike,
The information on the website can be hard to find, if you are not familiar with it. I think you would find it under "questions and answers", then click on "identification" and scroll down. Typically, the proof date would be found near the bore/ case length dimensions and would be expressed as a number representing the month and year (such as 736 meaning July 1936). Since the rifle was proofed in Zella Mehlis, rather than Suhl, there will likely be another number under the date, this number is log number and identifies which number it was of the guns proofed that month. This number should not be confused with the date, but sometimes is.
