Vintage Olympus GB Microscope in Original Case

This is an Olympus GB microscope in its original case. The GB model was launched in 1949 and was based on the GK body. It has a rectangular stage and could be used with a binocular head. It has the serial number of 236170 stamped on it - the GB model was made for a number of years, so Im unsure of the exact age of this one, but I would think 1950s, maybe 60s. This microscope comes with two eyepieces - a 7x and a 10x. It has three objectives and comes with some slides, a blue glass filter and other accessories (see view the photo). I dont think that it saw much use at all - there is no sign of wear, everything moves smoothly and it appears to have been well stored. The case has its key holder but is missing the key and there is some scuffing to the exterior of the case. The case measures 8 by 13 1/2 with a height of 11 3/4 including its handle. The case with contents weighs 20 lbs and 6 oz, without packaging. Nice vintage microscope in what appears to be excellent condition.....please click on any photo in order to enlarge.....
