We have these oldies but goodies made by Sankyo, Toyo, Fuji or Narco before that. Some have Robbins impressed on their clear casings. You may also remove these from their casings for use in your music box.
We don't have a complete listing of this inventory, but when the black with white metal Sankyo movements or the Sankyo Gold movements are unavailable we can substitute many of older requested tunes with these.
There is a small difference in measurements. The mechanism in it's clear casing, measures 2 3/8" x 1 7/8" x about 1 2/8" high ...just a tad larger than the Sankyo in the white casing which measures 2" x 1 3/4" x about 1" high.
A collectible piece of music box history. They don't make them like this anymore.
To order : https://www.musichouseshop.com/store/Movement-Japanese-18Note.html for our most complete Japanese 18 note List. If the tune you wish was manufactured in a ready made movement we'll find it for you or give it our best try!
