That is why so many people seem to be breaking guns and selling them piecemeal on fleabay as 'Spares'
I reckon you could get
£30-40 for a good unsplit stock
£25 at least for the trigger block
£5 for the piston assembly
£10-20 for the barrel/cylinder assembly if in good nick
£20 for the rearsight at least
£5-10 fr the underlever assembly
£5 for the screws etc
Total by my reckoning £100 at lowest estimate ( all plus post!)
Jobs a goodun !!!
And you can sleep easy knowing that your bits probably contributed to getting four or five scrappers back shooting again.....
Food for thought........
