Rich, I believe your Kodiak is a 64" 1953. It's definately collectible, as is any early Bear bow, especially the Kodiaks. The high 70# draw weight is a plus toward the collectible side. Since it belonged to your dad, and has such an awesome history, I'd leave it just like it is. I don't want to insult you at all, but to put snakeskins on this bow would be a sacrilege. I don't know how well it would work over fiberglass anyway. Any collectible bow is better off left original and not re-finished, however there is a line that can be crossed where the value would go up some to re-finish. That is, when the original bow is in bad enough condition to merit it. Yours looks really good, and typical of this year. I'd keep it just like it is, shoot it, hunt with it, and never let it go!
But that's just me. You will get various opinions from different folks. I'm no "Bear Expert" :D as stated above, but collect a few old bows.
Take Care, CKruse
