The instrument also bears Serial Number , which is engraved on the side of the brass ocular holder on the top of the body tube see image. Included with this listing is a cut from the Catalog that shows one version of this latter instrument that has the screw mounted Abbe condenser in the substage.

Mid teens Bausch and Lomb jug handled microscope with a mechanical stage and Leitz Wetzlar optics. It included a bunch of occulars and what looks like a camera attachment that screws onto the tubus after removing an access plate.
You would push the sliding tube in and a prism re-directs the optical path to the side. The other end has a cup surrounding a tube that takes an occular or a modern CCD cam for that matter, but one corner of the mount is bent a little, and I will not install it. If I can resist. This one did not come from the medical school, I was forced to sit horrified and watch as my hands, of their own volition, reached out and purchased it off eBay.

This microscope was originally constructed in compliance with a generally expressed demand for a simple, relatively low-price and well-made instrument, which is adapted to every grade of work, and claim that in it we have a model which possesses, in an eminent degree, these qualities. Probably no low-price instrument has ever been offered the public, which has been so favorably received and met with such ready sale as this.
It is of chaste design, its parts are all calculated to bear the strain of every-day work, and on this account and because of its simplicity, it may be used by inexperienced hands, without detriment or injury to it. This microscope especially recommends itself by requiring a smaller pecuniary outlay than any of similar construction, and may be supplied with valuable additions, such as our revolving and glass stages, mirror-bar with adjustable mirror and sub-stage, all of which greatly increase the efficiency and add but little to the price of the instrument.
The tripod base, pillars and arm, are neatly japanned; the axis is arranged with strong bearings to allow inclination of the body to any angle. Coarse adjustment is by perfect rack and pinion, provided with tightening screws; fine adjustment by a delicate micrometer screw, acting on our patent movement. As at present constructed, the arm is considerably lengthened to allow the more convenient use of low-power objectives, as well as the double, triple and quadruple nosepieces.
The stage is of brass, circular in form, thin to allow great obliquity, but of sufficient strength to be firm under manipulation.
