Any ideas?

It has Oliver's of Knebworth on it but no other markings. 9foot long 2 piece.
No idea of what weight line either.
Metal ferrules and a nice little stopper.

I'm guessing it's some sort of cane

......not necessarily. I may be sticking my head above the parapet here, but the absence of any visual grain on the "wood" makes me think it might possibly be tubular fibreglass.

Many rodmakers continued to put elaborate intermediate tyings on their products, even if the rods were not cane, because of demand. Many fishermen didn't like the 'new' rod material (often with good reason it must be said!) and resisted the change from the traditional, so many makers put these totally unecessary tyings and metal ferrules on, just for appearance' sake and to ease their rods into the market.

As to line weight, if it has an action like a jelly on springs, try a WF#6.

....On the other hand, I could be totally wrong!

Definitely hollow fibreglass. Oliver's glass rods came as kits or finished rods; this one is the latter, as the two-colour whippings are quite distinctive. Many of their early glass rods from the mid-late sixties were light brown when new, but the resins used tended to fade from exposure to ultra-violet light, so today they often look yellowy-gold. Some age unevenly and can become mottled. It will probably take a 5 or 6 line.
