Has anyone seen a Gretsch Sop like this?

For sale on another site, I'm curious. Looks to be quality, but no info to be found. Recent, I'm sure.

Well who'da thunk you'd be stumped?

Looking at the catalogues on their website here http://www.gretschguitars.com/support/catalogs , I think it's only fairly recently (in the 2013 catalogue) that Gretsch re-introduced ukuleles as part of their 'roots' collection, and the one you have pictured there doesn't seem to be one of those, so I would think that one pretty definitely isn't a very recent one. Even more recently Gretsch seem to have stopped using friction tuners in favour of geared (shame!). Had they not done that I'd have been very tempted to buy one myself.

No, it's definitely a recent one. The pin bridge is unique though. Maybe an owner mod? Or a factory prototype?

It's the same one for sale on FM, which the seller says it's a one-off prototype.

Maybe it is a one-off. Seller doesn't seem too sure though, thus the inquiry here.
