Like many have already stated, I am familiar with the metal riser Carrols, but this is the first I have seen with Wood risers. Back in the old days, Carrol made some fine tournament bows. I was unaware of any hunting models.
Like many othr great brands, these were bows made by individual bowyers on a small scale when most of the better known, more popular brands were mass produced, like Bear, Pearson, Wing, Widow, etc... When we used to see these "off brand" bows, we always assumed they could not be as good as the major players. Boy, were we wrong. Thes bows are now some of the most collectiblebows out there because of a combination of their rarity and being solid shooters.
You have a great find. Enjoy it.
