Appears to me like the back of it might need a look, and possibly some attention - does the back close snugly, and the lenses fit correctly? The orange cast in that picture looks a bit like fogging due to light leakage.

Or, if you hadn't had the film developed for sometime after the pics were taken, and hadn't stored it in the fridge, it could be deterioration in the film's emulsion. This will inevitably occur over a long time, and typically presents as an orange cast in colour film. Alternatively, if the film had been exposed to extremes of heat, this would speed up the decay of the emulsion. Prior to processing, was the film/camera sat on a shelf in the sun for a while, for example?

If it is as ropey as you suggest, I'd chuck it away a spend a bit more money here:

They provide an excellent service, and if your local branch doesn't have the used item you require in stock, and there's one elsewhere in the country, they'll send it over for you! Might I be so bold as to recommend something like a Pentax K1000 or ME Super, or a basic Minolta?

Good luck! :o)
