Theoben sirocco 2000

[Gerwyn]

Hi All
I'm new to this so please bare with me, I bought a Theoben sirocco 2000 today for a bit of a fixer up project and discovered the cocking lever has pulled out of the shoe it fits into to and also the safety does disengage when you cock it unless you take the stock off. I didn't pay much for it but it seems to nice a gun not to have a go getting it fixed. Does anyone know who could fix it or is it just going to be a ornament in my collection. Pictures attached

Any help would be great
