Based on initial research we believe this is early 1917. Serial number is 198284 and you can use this to find the date - just Google it. These microscopes were made from the early 1850's to the last 1970's. Microscope is in excellent vintage condition, with no significant scratches or chips from the black paint.
Two-sided mirror with revolving "condenser" below the large stage. Wood slide or specimen carrier. The latter two slot cleverly into case. Sadly we have no place to display this, so are offering it for sale. The wood case has very unusual finger style joints - unlike traditional finger joints which are straight, these are set at an angle. As always, please carefully review the pictures as they form part of the description.
