Bally's 'Sir Nudge'

Would like to restore this to payout the tokens again.  It's missing a coin tube for the 10p tokens and the coin shoot that sits above the tube and directs coins form the coin acceptor on the front panel (excuse my limited buggy-speak here).  Also would like to convert the 10p payout back to the 'old' 10 new pence/florin and think I need a different size coin puncher in the payout mechanism as it has been adjusted previously to pay out single 10 p of the new variety - if anyone can help.  Thanks
