Hello MMD,  I just bought what appears to be a 4-overture music box
which plays with mandolin pinning over 2/3rds of the cylinder.  Please
view two tunes on the YouTube link:

Can anyone identify the two tunes?  Any idea on a maker for the box?
There is no evidence of ever having a tune sheet (no pin holes).
Did any music boxes sell without a tunesheet?
