Oh, that is lovely!

Pashley is a bike manufacturer; Phillips was primarily a manufacturer of bicycle components, though they also made bikes. Until they were bought out and consolidated with Raleigh about 50 years ago, a lot of different bicycle manufacturers --all but Raleigh, I'd guess-- used Phillips components. They could also have used other components, such as the German parts you noticed on the wheels. So this is a Pashley, which is a very good thing.

Collectible? To a collector, yes indeed; it's a matter of finding one. Shouldn't be hard, though. If you were in my neighborhood I'd try to buy it myself, but I'm not going to ship it across the pond.

Worth restoring? I don't see anything wrong with it; clean it up a little, polish the chrome, and it's perfect.

Worth selling? Well, if you don't want it, and aren't using it, yes; easier to sell it than to find another one, for sure.
