Yes, they were made in Japan. Why did you say "promotional pieces like this"? Do you know something about the Royal Crown (Not Crown Royal,LOL) Binoculars? They look like they were made in the forties, although, I have no way of knowing. They're marked 6x30, field 7.5, no 60559. They don't appear cheap and have very good glass. I just wish you didn't have to adjust each eye separately. I personally like the middle wheel on my B&L.
