Or point me in the direction where I can find out as I understand you can date them from the serial number, thanks

The serial range of cag marked binos that I have on file start at 3981 and finish at 308729. I do no doubt that there other serial numbers outside this range that I have not recorded.

I am not aware that cag maker marked serial numbers will help you date the binos you have posted. That is because (at least as far as I am aware) the Swarovsky records (if they exist) are not accessible to collectors.

Your best chance of dating your particular set is to figure out which period the Δ grease symbol was used. I have not undertaken any research on the matter (but see Seeger at pages 122-123). I assume that more versatile greases needed to be developed by the Germans to cope with the extreme temperatures that they faced in Russia and other places such as Norway and North Africa.
