Help with old knives

[chadm169]

Hi there! I found these knives in a set of regular silverware from an auction. They are very worn but I can make out an iron cross W R keystone, barely. I have found some photos online of the same symbols and initials but not in the same style which makes me think they could be a bit older than some I've seen. I know they're hard to see but the initials look like older style with a line through the W. Any help to identify age/history would be greatly appreciated!

I couldn't make out the markings too well and don't have info on those, but I've seen a lot of nickel silver knives that look exactly like those
