Help identifying my razor

I recently traded for a couple blades. One of them is what I'm told is a Stiz Russian SR. However when I research them I never seem to find this razor or scales. I also have noted that there does not seem to be any etching or stamp on the blade as noted on other blades of the same manufacture.

I can't get a good enough signal where I am to post a pic. The box is green and has all the appropriate markings for a stiz. The razor scales are gray and simply stamped YMPO and then the odd looking OE symbol. As I said the blade is unmarked.

Hard to tell without seeing a picture but like you said the odd looking OE symbol is Stiz trademark.
