I'm sorry, but you'll never get it back. Even now it is probably growing a bandito 'tache and being briefed up for an attack on a PIRA ASU at a Gibraltar petrol station. It will never be the same (the trauma, you see). It could even be the one I used to terrorise recruits in the late '80's- they wrote "CPL AUSCAM'S SCROTOID BASHER" on it and gave it to me as a goodbye present.
It's had a rough start in life. It needs help, not punishment, poor thing.
