I have one that is different in that it has some binding on the slightly smaller body, the pegs are interesting in that they a tapered metal set in a fitted metal insert and are the lightest tuners I've run across. It's got the same label as yours. Love that flamey mahogany, that I've seen on some Regals, wish they would have used it on mine.
Also have a soprano Banjo-uke that is my go to Dixieland player. Have to keep a sock in it for most venues.
I've heard that the SS Stewart shop was used by Regal for their higher end production ukuleles.
