Many thanks Denedium. How do I measure if it is 68mm? Is it the width of the frame? Sorry if that's a really stupid question. Would it help if I sent a photo or two?

I have a 10 speed Raleigh Carlton Cyclone. Bought for my 16th birthday back in the early 80's and still in use. A 'few' scratches and a bit of rust but still has the original tape on the handlebars, original short mudguards and I even have the original tyres, although I have swapped them for more chunky Michelin's as they punctured too easily.
The one thing that I did have replaced about 5 years ago, due to me being stupid and shredding the thread on the original crank arm was the bottom bracket and chain set. Recently, this is working itself loose. I've taken it to a bike specialist who has tightened it up but it is working itself loose again causing the pedals to wobble and making changing gear difficult as I ride along. Because of the age of the bike the guy at the shop said it would be difficult to source a new bottom bracket as that type of assembly is obsolete, but without it the bike is shortly going to be un-rideable.
Can anyone advise me where I may be able to find a replacement crank. Does it need to be specific to a Raleigh Cyclone or are these things standard. Are they based on framesize?
As you can tell I'm quite attached to this bike so any helpful advice would be much appreciated.
Thanks

Hi. Thanks for the links. I measured the width quickly this afternoon and it is approx 68mm but need to capture accurately as it says in the article that 70mm is also common. Not going to be easy to measure the length either. Do I need to remove the cranks to get that accurately? BB currently out of stock but if it does turn out to be right fit etc I'll certainly let you know.
