Hello, I joined this forum in hopes to connect with a someone who really knows their rods. We acquired this rod years ago and it has never been used. It's a beautiful rod and obviously made by a true craftsman. I have searched the web and the only hit I found was possibly made by a custom rod builder from Venture, CA. the company was called ARC, American Rod Company. But they must have closed because there is no website or contact info. The other story is, it was made in Sacramento, CA by a company of the same name. Again, can't be confirmed. I have been told it is a salt water rod and told it's a rod for fishing steelhead. It's a four piece, has 12 guides and is 9ft. Someone said the 1290 on it indicates it's a 12 weight, 9.0 ft. and that's why is an ocean rod. Someone else said the 12 indicates the number of guides and it's too light to be a 12 weight. No one knows what the 4MP means. Anyone who can shed some light on this would be greatly appreciated. It has become a bit of a debate.
