S.S.Stewart w/14K Medallion 1926

This amazing ukulele was sold by S.S Stewart which had stores in both Philadelphia and New York City but it was made by Regal I have been collecting ukuleles for over 28 years and have never come across a ukulele with a 14K gold medallion inlayed in it the Medallion has the initials MPB 26 I do not know what the MPB stands for but the 26 must stand for 1926, besides the 14K medallion there are mother of pearl dots on the end of every tuner.  

Not for sale; currently in a private collection.
