Interesting cello bow. Bought it thinking it was low grade pernambuco and after cleaning, it appears to potentially be nice. Not counting the repair :(

Can’t read the stamp very well at all. JOS??? ?????R 

What is the wrap? The white is translucent and the black is very flat. Whalebone or a nicer plastic? 
Thanks all!!

Hit the wrap with black light. If it glows then it’s whale bone.  If not then it’s probably some sort of plastic or synthetic material

Thanks! It appears to be genuine.

Heres one ive just photographed next to two pieces of turtle shell.

nB. i just remembered why the result of the turtle shell appeared like shellac, its because it was from an antique turtleshell and was probably varnished with shellac. (hence the tan/orange  colour)

Ive added another photo with some of the shellac varnish removed and it glows more like it should very similar to dried animal glue protein

Very interesting. Apparently tortoise shell (frog) fluoresces as well. Is ivory fluorescent?

Interesting that these 2 ivory frogs fluoresce differently. The top one is much newer than the bottom one but they are both ivory.
