That bike has been listed, a couple times. When zooming in on the rear hub, it appears to say "56" (eBay pics seem to almost never be clear); not "50" as the bike is listed. For 1950, I'm thinking it should have an enclosed chainguard, unless they didn't put them on this nameplate. I'm not sure on that.
