I picked up a pretty cool taper attachment on craigslist yesterday. It is made by the "Master Taper Co". Anyone have any info about these? It is missing two parts of course but i`m sure someone somewhere has them. I`d be interested in a scan of an old catalog or owners manual as well.

It is nearly exactly like this: https://www.ebay.com/itm/56-Master-Universal-Lathe-Taper-Attachment-For-Lathes-up-to-24-Swing/163194787141
The difference is its only about 18" long which makes it a great hobby size. it does clamp on the rear flat ways of most old machines like Atlas, Clausing, Logan.

Looks like the Keene Electrical Machinery Co. marketed a few things in addition to the the taper attachment. I found similar ads in Popular Mechanics / Popular science for an internal gauge to measure splines, a rotating dead center, etc. And they had spearmint gum too!
