A wind-up Phonograph made by Micro Seiki?

So I'm going through this this huge lot of antique turntables, some NOS and I come across these three large boxes, heavy too. They are from Micro Seiki corporation and as luck would have it they had never been opened. Upon opening one a large, heavily padded envelope sat on top with the owners manual in Japanese print. They were sitting on top of some other cardboard and foam packed parts. Inside was this large brass handle. As I unpacked further I can tell this is not a turntable like the rest it's a phonograph like the old wind up style RCA-Victor and Thomas Edison but it's brand new in the box and made by Micro. I stopped unpacking right there and went to the internet to see if anyone else has one of these or had ever heard of one. The answer is NO.

So I have this Micro Seiki Phonograph I'm trying to figure out what to do with, complete with a large tarnished copper horn that appears to mount to the top. It's in three boxes and has a small wooden box with the wind up motor and speed controls. I'm sure this was some sort of promotional in store display or something from back in the day before Micro went out of business but what a cool find and a great conversation piece.
