Petersen vs Swaggerty
Yours was made by Swaggerty of SouthCal, mine Petersen of Ohio which ripped off Swaggerty's design. Yours comes in 3 sizes, you have the largest. Mine is either a "Polk-a-lay-lee" (because it had a decal saying that and sold out of Polk Dept. stores in Chicago) or a "Wander-a-lay-lee" (probably the latter and dark stained wood is one of 4 finishes. Tunes and plays better than I originally thought it would. All of these ukes were made in the mid 60's and I've seen them selling online from $75 to $500.
