This Leitz Wetzlar Ortholux-Pol Microscope. This model can be dated to around the mid 1960s by it's duel illumination potential but predates the more modern square design.
This model has dual optical outputs and the potential extension for a camera output at the top.
For measurements this models Vernier scales allow for a measurement of 0.001mm of movement by the baseplate alongside the 4 lense options.
The model comes with the original lamp and transformer, the specs of which are in German on the transformer itself.
Happy to answer any further questions, it's a really interesting piece of kit.
It's a hard item to price as well
