That is a fabulous bow.  Great shape, great paint, and that birdseye maple is just wonderful.  I love it.  I may have to have a go at one myself.  There doesnt seem to be much birdseye maple over here in the UK, but I have found a handy luthier's website, where I can buy a long thick piece which would otherwise become a neck for an electric bass guitar.  I like guitars (and basses especially), but I think that I will have   to buy some of that wood for a bow belly.
Would a bamboo backing be too strong for the birdseye belly?  How does the birdseye maple work?  Very hard or OK?  
Keep up the good work!
