It depends a little bit on how much you want to get out of it. I had a
quick look on eBay UK and based on completed sales it looks like the body itself is worth around CHF30-40 if you're lucky. So unless you're really commited to getting some money out of the camera, selling it is likely to be a lot of work for not a lot of money.
It's probably the same story with the flash, as most people now want flashes that will communicate directly with their AF SLRs.
The lenses, though, will almost certainly have some value and are very easy to sell. If you don't mind posting the items abroad, I'd probably stick all the various bits and pieces on eBay in the UK and take your chances. I would definitely split the kit, though -- you'll get more money for the pieces than for the collection as a whole.
