A well maintained Arcos Brasil carbon fiber German Bow. It came with the Shen Bass that I bought new in 2010. It sees little use as it's quite light: Johnson Strings offers one that weighs 123.2g.
Upton Bass rehaired it with black hair.
The imitation whalebone sticker is beginning to unpeel but it does not affect playability. It's there mainly for visual effect.
Bow length: 30".
Hair length: 22.5".
Frog height: 1 3/4".
New, these are offered at over $400 (Johnson & A440).
Asking $295 shipped Conus.
