Lol Kim I see you are on the hunt as I was when I had that one. I emailed and sent Dave Windauer about 30 pics and he swears its not a Silvertip of any vintage. His professional opinion was that it was either a lesser known bowyer or an 'ode to' a Silvertip perhaps. Good luck! I also spoke to Tecum-tha (Roland) and he is a friend of Chastain and is also positive it is not a JK. I'm dang curious either way and hope you succeed, I did not have the time to figure it out. Pretty cool bow either way and shot a 700+ grain arrow when I pulled it back behind my ear like nothing.
