I can give you the choice of three but I can't make any guarantees on condition.
Look for a new replacement, they ain't that expensive. I got a Kafer carb (34 PICT 3) for my bug from ebay.de cheaper than anyone I could find either here, the UK or the states. It works grand and doesn't leak like some I've heard about... I think there were 30 PICT carbs available at the time I looked too...
