The serial on this guy is pretty close to this confirmed 1915 Weymann style 50 so I suppose this one probably dates to 1915 as well. Anyhow, this is the plainest Mandolute I've personally worked on, though as far as mandolins from the time go, it's anything but plain. Weymanns are quality instruments that I think of on the same level as Vega and Martin flatback models. They're a bit different, tonally, though: they sound like an extended-harmonics, fuller-depth bowlback mandolin more than your average flatback. This means that they have a sort of crisp sweetness followed up with a lot of sustain.
My work on this mando included a fret level/dress (which ameliorated a tiny amount of relief in the neck), seam reglues, and hairline crack repair/cleating on the lower bout top and also next to the fretboard extension on the top. I also cut a new bone nut and new, compensated bone bridge and fished a suitable tailpiece from my parts bin.
The result is a great-playing (1/16" at the 12th fret), sweet-sounding (perfect for folk or Celtic circles) mandolin with a "medium" 13 1/2" scale length and professional feel.
