Vtg Reuge Switzerland Oscar Heiss Co St Basil Cathedral Music Box

Lovely little music box works.  I believe it has 18 notes, but I am not certain.  Unfortunately I do not know the tune it plays.  It measures approx 2.25 inches tall x 4.25 x 3.  Some minor scuffs, but overall good condition.  When I count the notes, the one on the very end looks like it is missing, but it is most likely just the way it was made.
