Banjo Ukulele Haven page - has found the only photos I've seen of this uke with the Buster Brown shoes logo on the vellum. It's a great find, and everyone I know who finds this type - even without the logo on the vellum - refers to it as "the Buster Brown" due to this association. As David points out, this was a promotional version of the model, created to help sell Buster Brown shoes.
It's a truly handsome ukulele, and though not as heavily decorated at the Rose, I think it's the most attractive that Stromberg-Voisinet produced. So what makes the Buster Brown unique?
Well, its not the pot, five-piece neck and fretboard, which are actually identical to the Rose's - and as you'll see, they were made with a plain fretboard and headstock with no logo - or made with the signature S-V Pearloid treatment and white celluloid fretboard binding.
So - it has to be that resonator and that chrome flange with portholes that's special. And notice how the pot of the uke actually sits directly against the flange - that's not only unique among S-V ukes, but also very rare amongst all kinds of banjos.
Just recently, a Buster Brown (sans logo) came up on eBay that showed just how the resonator attaches - note the block that serves as the spacer.
Also note that the brand name 'Elton' is stamped into the flange in the place that would normally be placed under the heel. We've got to thank the seller for not attaching the resonator right to show us that detail.
Elton is the Chicago-based company that made capos for ukuleles, banjos and guitars in the twenties and thirties, but here, their logo on the flange seems to indicate that that Elton manufactured the flange for Stromberg-Voisinet.
There's also a version of the flange made for the "Buster Brown" that has a raised 'grommet' around each resonator hole; whether that version was manufactured by Elton, I can't say yet.
We have a few more styles of S-V uke to cover here, but next time - onto something a little different. Until then - keep on strumming.
