Help! Mauser-Vergueiro bolt + safety stuck

[Jowi]

insert a cleaning rod down the barrel

Thank you for your reply. I'd like to note that this rifle has been made unusable. The top of the barrel has lead in it, not all the way down though. This is no issue to me as I don't intent to shoot this gun.
The thing that bothers me is that the bolt, the safety and the ammo button do not work. I only want this to operate for the feelings, the sound.
For now, it's just looking at a bird without wings.
