I have in my possession a Kunnan, 8ft, CG7205 AFTMA 6-7...
Not sure if the 6-7 means 6-7 wt, but the rod in general feels fairly noodley. I wouldn't be throwing a 6wt line on it, I think its more of a 4wt or less. Feels that way anyways.
Any info that could be provided would be great. I don't think its anything special, but you never know. I didn't search around too hard online, but I did see vintage in front of the name a few times. Likewise, If someone is interested in purchasing it, send me a PM and we can talk details.
