I have a few old tip sections around. I can sell you one for $74.99.;-)
Seriously though. I think you can probably get a new unfinished blank tip made for about 100 bucks, but I don't do that.
I have some antique tip sections around, but I'd have to think long and hard about parting with one. but if I found one one that is not mated to a rod i have, I'd probably let it go for cheap. If you have no luck elsewhere, drop me a PM. I'd need a bunch of measurements to compare tapers to get something similar. yu rod was probably originally a 9 foot. Some pictures of the rod including reel seat and ferrules would also be helpful if they are still original. Any pictures of before restoration? At one time I wasn't bad at helping to identify the old production rods but I'm a little rusty.
I don't visit this page often, so feel free to send a PM if you wish to discuss.
