This frame and forks is a bit of a curiosity.
It doesn't seem to fit any of the well known Raven range and may be an early version with a short production run.
It looks the same as one advertised and discussed on the ctc forum a couple of weeks ago.
Note the painted head tube badge, rather than the more common current stuck on badge, and the model name decal is just "Raven" rather than "Raven Tour".
The colour scheme is not one from the past ten years or so.
The front forks have the brake bosses on the rear like the Sport Tour.
Also, despite being advertised as an expedition tourer, the front forks have no rack braze-ons, only mudguard stay braze-ons.
An interesting beast.
