Hi, madeline! Well, I once had one of that exact same make and model... but gave a bunch of scopes to a guy from (DC, Virginia, New Jersey?) about twenty five years ago. I think that went with them. He literally loaded up his big van to the gills and returned overloaded and happy. And my barn had a wee bit more space, so I was also happy. Mine was in very good shape, but I recall that the vertical fine-focus mechanism there was hung up... probably just dried out grease, easily fixed. I always liked that one, because of the nice flowing artistic presentation and the unusual mechanism.
Beyond that, I'm afraid I'm not into the heritage of microscopes... other than the vintage B&L are uniformly wonderful. Yours looks like it was a real workhorse but otherwise should refurbish nicely. Can always say the ~patina~ gives it character... which is my attitude on these. Just cleaned up and functional... stick it under a bell jar and it takes on a museum display character, worthy of a place of honor. Tom
