Webley MK1 pistol project(?) valuation

[lodmoor]

My clearout continues. I have found parts of a pe-war slope grip Webley MK1 serial number 64656.

The parts consist of main frame, piston, spring guide (matched no.) trigger and guard, sear and spring, trigger adjustment screw, rear sight and screw, grip screws, one pin and the pivot screw (but not the screw at the other end).

The question is, please, what is this lot all worth as a project?
Or as a collection of spare parts?

A quick trawl through Chambers of the components they had listed came up with £120 without the body and front end (spring guide) but that is Chambers prices and I don't want to be laughed at sooooooo, realistic valuation(s) please.

Not interested as spares?

One more bump before I put it elsewhere.
