I think you might be right. The seller was saying the same thing. Said it was a 6-7 wt. I will have to wait and see. Unfortunately I will be gone before it arrives.
But it is labeled for a 9wt full sink shooting head or a 9wt WF floater. Might have to skip vacation. Lol.
[Additional information added 8/10/22. Tom]I would like to first mention to the moderator that I attempted to add this to my original post but the only way that I could get the full editor with photo posting option to function was to either edit my existing post or create this one. I apologize if there is something that I was missing. This is also my first attempt to upload photos, so do not be surprised if I mess up. I will try to do my best.
[In future, please add the new information to your post by editing the existing post. You can't make several posts in a row with our currrent software setup. Tom]As posted earlier, I purchased this rod and an FF90 from the same seller with the intention to physically compare and then cast them.
I am also not making any claims about expertise, just my own observations and trying to be as factual as possible.
I am also presenting this rod only as a unique curiosity and I am making no claims about is history or authenticity.
Upon inspecting the rods, I immediately recognized that an apples to apples comparison was not possible. The B series and C series are two distinct animals.
The reel seat on the FF89 is .730 dia, the locknut OD is .860 and the cork is under 1" in thickness. The butt to top of cork is 10.5" The reel seat length is 3-3/4"
The reel seat on the FF90 is .885 dia, the locknut OD is 1.15 and the cork is over 1" in thickness. The butt to top of cork is 11.5". The reel seat is a little over 4-1/8"
The FF89 is a low production number B 2803. The FF90 is a C 9592.
I decided to proceed with the casting test, but having a B series FF85 and FF80, I decided to include those measurements including the tapers after the casting test.
The FF90 has a missing sticker but the glue residue indicates it had the large sticker as seen on another forum members rod (His a C 3824)
That would mean its a 7-8-9.
The FF89 is marked ST9SWF9F. No hyphen between the two line designations. There is a poster whose photos are missing with a FF90 B Series 5891 with otherwise identical markings except with the hyphen. (Would love to share taper measurements with him if possible)
So I started with a Rio Striper WF8F. (Closer to a 10wt at 280 grains. Printed on box).
Both rods, no problem, simple slow smooth pickup and shoot the head plus about 20' of running line.
Upped to a Rio Coastal Quickshooter XP Wf9I (Rio does not post but the Internet gives it around 375 grains or a 12Wt.)
Again, both rods, no problem, simple slow smooth pickup and shoot the head plus about 20' of running line.
Dropped down to a standard WF7F trout taper. Both worked fine but started noticing the FF90 to be a little slower and less crisp with the lighter line.
To add more data, I brought the FF85 and FF80 into the test and surprisingly they also handled the lines with minor adjustments to my stroke.
While waiting out a brief downpour, I got the idea to go down two steps and grabbed my Martin MG-3 with a budget WF 5wt.
I took into account that none of these rods would static balance, but with the 8wt line on a fully backed Lampson Liquid, only the FF90 and the FF80 balanced.
Probably due to the longer grip on the FF90 and shorter length of the FF80. both the FF89 and FF85 balanced about an 1" forward of the grip.
Now I was wondering if the heat was getting to me. The FF90 struggled a bit. Really had to slow it down and add a single haul to the forward cast to generate some line speed. The FF85 and FF80 cast adequate but then I was pretty impressed when the FF89 sent out 60' of line, not counting the leader or rod. As an FYI, I used a 9' 1x leader with a garden sized piece of yarn for the test. I am going to attempt to post some photos and then with add some of my observations and measurements of my B Series rods. It was not what I expected.

Tom]A minor correction: the 5wt line has a 7.5' 4x leader nail knotted to the line. Much smaller piece of yarn. I got it in the clearance bin at L.L Bean. I grabbed a 3wt also for my FF535. for only $19.99ea.
