How to open Sankyo Clock mate?

You have a 1976 clock mate made by Sankyo. That has a musical clock toy with a spring to rewind. Since, you are unable to rewind it, you want to take it apart to repair ir, but you cannot see how to open it, as the hole are very small and you do not see any screw to drive. I have an idea on how to open it without breaking it.

These old toys from the 60's and 70's are usually wielded together, so you'll have to pry it open. I recommend a flat head screwdriver, these toys are held together by glue, sometimes a blow-dryer heats up the glue so you can pry it open better. This video, shows how a person opens up a 1960's pull string with the glued plastic: https://youtu.be/56G09ublEWU

Examine the toy one more time for screws, or snaps, or signs of glue. Be very careful if you try my method of prying it open, the wind in the back of the clock connects to the yellow arms of the clock in the front, its a music box inside of the toy. Since you can't wind it anymore the drum of the music box or spring has come undone. The spring is 40 cm and tends to bounce up at peoples faces or eyes, so be careful when opening this old toy.

If the eyes move back n forth that means there is an interlocking gear system connected to the music box, and if anything else moves on the toy it is connected to the music box as well. The music box inside is broken and may be challenging to fix, as you might have to replace the music box and interchange the mechanism. Sankyo made a whole line of musical toys and music boxes. such as: https://youtu.be/KNgKVNEM5zQ

I hope this helps!
