【Contrabass Bow / German】C.SUGITO (Used)

This is an accessory that came with a domestically produced double bass manufactured in 2010. Based on the bow's shape and the C.SUGITO engraving, it is believed to be either a Stan-A (German) or Stan-B (German), but the details are unknown.
Black horsehair is currently strung on the bow. It appears to still be usable, so it has been left as is. The tip of the frog was chipped, so it has been repaired by a workshop (photo 5). There is some fraying at the tip of the silver winding.
At 143g, this bow is a bit heavy for me, but it produces a soft tone.
