When I got my gun, it came with a spare of each. Towards the end of last year it started not holding half cock and full cock was very light, under legal weight. So I put in my spares. It's working again, but the action is still a bit springy, as the replacement parts themselves were used.

I'd like a new or almost new main spring and tumbler to have in my parts box as a back up. VTI might have them, but they don't list the Pedersoli sharps on their Pedersoli page; so before I give them a call I thought I'd ask here and see what you have.
