Daveslot is, of course, right but if you're interested here is a little more info on the type of machine.
You can find many photos on this site of what the machine looked like when it was made, just search for Beromat. The reason it got rebuilt is this. Slot machines were only allowed to be built in Germany in the early 50s if they were either destroyed or exported after a very short life (I think 5 years) so hundreds got exported to the UK after their German life. Some kept their original cases and were re-branded to take UK coins but a large number had their mech's removed and put into dozens of different (what were considered at the time) modern cases.
As the mechs were only expected to last a few years they were made of very cheap metal (often called "pot" metal in the UK) which breaks very easily, but here we are 60+ years later and hundreds are still going strong. The weakest part is perhaps the coin slides which are well known for breaking with age related metal fatigue .
I've seen the "Roma" before and believe it or not it's one of the better looking cases.
