Replacing a door handle spring?

Apart from electrics/electronics, my DIY skills are poor, so I'd much appreciate advice please. The spring of the door handle on the downstairs loo has been getting progressively weaker for a year or so. As you see from the illustration, it can't even keep the handle horizontal. In fact it barely keeps the door closed. The obvious solution would be to buy a new unit, but I can't find an identical replacement for these 26 year old handles. And all downstairs door have matching ones. But perhaps someone here knows of specialist sources I could try please? Failing that, how would I set about fixing it myself please? I have visions of bits springing out and proving impossible to restore correctly, but maybe I'm making heavy weather of it?
