On Facebook here in LA there's an Orpheum branded Mandolin for sale with the bridge lined up at the bottom of the f-holes. Any other give-aways? They're asking $300 for it - might be with a drive over to give it a try if it's the right pedigree...
Upon further perusal, it looks just like the one your_diamond has posted in the gallery... Might have to go take it for a spin.
I have a Stradolin labeled Orpheum. Excellent instrument.
