All the knobs seem to function. This has been sitting for at least the past 20 years in climate control storage so I'm sure it could use a good cleaning, lubrication service, etc. The lock on the case is broken and will need to be r eplaced..

There is a placard that states IBM as shown in the photo. These objectives are mounted and have a quick release. I have no idea the age of this microscope as I cannot find any similar to it so if you have any information on it, I would really appreciate you sharing with me.
