Hi -- I'm trying to get help to learn more about a "Criterion 4" disc
music box (I think a single comb type) originally owned since my wife's
great-grandfather purchased it.  The discs with it are 15-3/4" diameter.

I have seen an array of Criterion's from looking online but I am unable
to find anything on this model Criterion 4, such as a year or period of
production, etc.

My father-in-law is 88 and has asked me to see what can be learned about
it's history.  Thank you for any help you can provide or for referring
me to anyone who might help us.
