Several years ago, there were a number of companies marketing threaded EPs like the first two. They are definitely not microscope EPs. In the magnifications shown, Swift, Bushnell and Kowa Prominar come to mind.
The 3rd piece looks VERY familiar. But, to NAIL it down for you . . . I can’t! Sorry.
Some things appear to be what they’re not. When I was in the optics shop at Ft. Lewis, we were visited to a couple of “guru’s” from Tobyhanna, Pennsylvania . . . the keepers of ALL the Army’s night-vision knowledge.
The auxiliary scopes they brought with them (to teach us our jobs on the AN-PVS-6) were taught to us as newly developed instruments. THEY WERE, IN FACT, THE FINDER SCOPES OFF A RUSSIAN-MADE 6-INCH NEWTONIAN TELESCOPE. They didn’t know, and our guys didn’t care.

I've seen many microscope eyepieces marked this way in the past.
Yes, microscope objectives are marked with magnification. But 13X is not your standard magnification for a microscope--most common are 5x, 10x, 15x, and 20x. The reason is scale is important and trying to imagine what 13x is a bit odd--why not 10x or 15x?
I work professionally with microscopes and have a great deal of experience with them. That does not mean that there are strange instruments, but it is not "obvious" to me that those come from a microscope.

I'm beginning to believe my opinon was biased by the microscope condenser assembly lying on the table besides these.Actually all four items were sitting in a group together.I only wanted the eyepieces.Folks like yourself and Bill C,those who have made a living among optics,are what makes these forums such a valueable source of information.Still would love to know what spotter those two came from.Its clear here tonight so I'm hopeing to try all three out in the scope.

Trust . . . but verify ANY opinion; we're not infallible. I remember that time I made a mistake . . . back in '58, I believe.
