Every once in awhile I come across something I can't identify. If you happen to know more about items I would greatly appreciate you contacting me at leicom@mindspring.com

	This particular Leitz item seems to be a low power binocular attachment from the 1920's or early 30's. It's nickel plated and obviously attaches to some other apparatus.
	The 1927 Pearl Endoscope appears to be purpose built for microscopic observations of pearls to (presumably) determine their quality. The carbon arc lamp is an Ernst Leitz, Wetzlar lamp and the entire Endoscope is built around it. The assumption is that Simon and Rene Bloch built it and it was sold by J. Bouery-Veysseyre and P. Chassaing. The Patent (brevet) for the endoscope seems to be held by Chilovsky Perrin (if that is actually someone's name).  Obviously this was manufactured in or around Paris, France.   I have not found any references to this item on the net, and so, I know nothing about it other than what can be inferred and from an email from someone who wanted to buy it. (who told me it was a pearl endoscope) . Any information would be greatly appreciated.
	Nickel plated condenser with centering screws
	Micrometer eyepiece that attaches to something else.
	A specimen prep stand or….what?
	Appears to be a large stainless steel specimen stage.
	Masks, pointer (?), and adjustable thin sheet on insert that replaces the glass stage on a stereo binocular microscope
