Westland?/Sankyo music trinket?

Hello! I have had this music trinket for years now, I have no idea about any history on it. The music component is Sankyo (it says it on the key) but I can not find ANYTHING on who actually made it or when it was made. The design is similar to Westland music trinkets but I can’t find anything on it m, and the bottom isn’t their design. Also, it does work, it is not made to have movement while playing, and I have no idea what the song is either. If anyone knows literally anything about this, please let me know! Thank you in advance!
