We don't know the history- item was purchased from estate sale. Cosmetically looks very nice. Please see item condition - it will come as pictured.
What we tested: The unit powered on. Nothing else has been tested. We put it as non working, however- it may be working and maybe needs cleaning.. etc The sliders slide little hard- so definitely it needs to cleaned, lubed.
It also come with manuals, brochures as pictured.
