We have an eyepiece at Mt. Wilson labeled "Masuyama" in a way that I've
always taken to be the brand, not the design. In fact, I believe the
design is a Kellner (labeled as such, IIRC). This is not a "normal"
eyepiece, though -- it's focal length is 100mm and it's in a 4-inch
barrel. We use it for visual observing at the f/16 Cassegrain focus of
the 60" telescope. I can examine the eyepiece in more detail, if you
like, when I'm back on the mountain in a few days.

I think I know where the eyepiece came from (perhaps 10 to 15 years ago)
but I'd have to check some sources to be certain.
