I think I've seen the case before, but that razor...now that is interesting. I found one exactly like it in my collection while doing some cleaning this week and love it. My razor is made in Canada and the handle is Bakelite. How about yours?
That looks to be an obvious mismatch to me. The ribbon case and the fact that it was from the Boston distributor leads me to believe it should be a single ring standard case. It has to be from the mid to late part of the first decade of the 20th century.
