Here are some quick pictures of a top quality 8x40 binocular made for Linet by Hiyoshi Kogaku. This one has the same body and mechanical works as the Swift Type 2 Audubon series. The "violet" coatings are different than Swift's, and yellow filters are built into the ocular covers. Notably it sports a 12º TFOV.
What this instrument showed me is that sometimes there can be too much of a good thing. An apparent field of 96º = ±48º is almost disorienting, particularly if one is at all inclined to look towards the edge. Otherwise, it's a very good optic, providing great peripheral cues if gaze is maintained near the center. Alas, I've never had it out birding. Others may have a different take on it.
Fan Tau had a 10x40 Linet, incidentally, but he told me it was deleted from his collection for some reason. He may have traded it.

PS. The s/n isn't dated, so this may be something Hiyoshi did for Swift products only.
