There are plenty of folks that talk about them being classics, but not too many are prepared to pay for them. I have a slightly older model that I've barely used in twenty years. The reason I still have it is that I don't consider it worth the trouble of selling.
I think your pricing is about right. Even in these days of wild prices for some older rods, I very much doubt the eBay seller is going to get £120. He'll be doing fairly well to get half that.
