Bausch & Lomb Microscope VTG 1908 B & L Optical Co Brass Metal Slide N. Y

Description

For your consideration from a smoke free estate.  A truly wonderful piece of vintage optical equipment.  I am going to do my best to describe this antique brass microscope.  But as I am not an expert by any means in this area please forgive any incorrect terminolgy.  Any questions or information is all welcomed and appreciated.  This microscope is made of brass and black metal.  All we have done is to dust this piece.  So the brass, although warm appears scratched.  It looks really retro as it is.  But I would think if you wanted to use it you would need to shine it up.  I leave the cleaning of these valuable older treasures to the experts.   The base is black and measures 5 1/2"  (longest) 3 3/4" (widest).  Base does have minimal surface rust (photo 7) and a screw that does turn.  I think this screw may tighten the base into place.  Back of base has a round metal plate that I think is brass.  It reads: Bausch & Lomb Optical Rochester N.Y. New York City.  The Bausch is a little hard to read.  The mirror rotates and swings freely.  The mirror measures 1 3/4" across.  The metal around one side of the the mirror has some age rust (photo 7) .  One side of the mirror magnifies the other is just regular mirror.  The mirror side that does not magnify has some silver loss around the edge (see photo 7 ), this does not seem to effect the visiblity.  The mirror will be removed for shipping as to decrease the risk of breakage.  The area that holds the slides is black, the two slide holders are intact with good movement and I think they are brass.  The opening in slide stage is 1/2".   The underside of the slide plate has a circular dial  I believe brass piece.  This circular dial  has 4 holes, I think they are used to regulate the light that reaches the mirror.  This  dial moves freely and the largest opening measures 1/2" across.  The microscope raises up and down without problems but may need to be lubricated.  At the tallest it is 14" retracted 11".  The piece closest to the slide stage is marked:  Bausch & Lomb 16 mm 0.25 N.A.  The eye piece is black and turns easliy.  I can see refective light through this without any problem but as I don't really know what I am looking at, all I can say is I see light.  The back knob seem to raise the back up and down about 1/4".  This knob turns without any difficulty.  I hope that I have covered everything, but please don't hesitate to let me know what I have missed.  This would make a lovely, gift to someone else or yourself.  But it is an old piece and again it is as we found it.  So please ask all questions before bidding.  We want you to be a happy and informed buyer and we really like hearing from you.  Thanks for looking, and please check out our other listings from this great estate.  Including some old slides that may or may not go with this microscope.  A really nice ebay expert informed us the # 37887 on the back indicates it was made in 1902 making it 111 years old.  Thanks fellow ebayer we really appreciate it .
