Rusty bastids that break down all the time, fairly simple to sort tho and great fun. I bought one before they went all that electronic way.
Used to stay in fife so I did as a boy used to go to the garison in kirkcaldy which became jackie O's. Met the bastid wife there so I did, wish it had burnt down when it was the garison, or washed away with the sea which used to flood the prominade in those days.
