Valjoux 730 guidance sought from a watchmaker

I've had a Wakmann triple date sitting for years, and the hairspring has always needed to be straightened. I finally pulled the balance and lifted off the hairspring, but I fear it's just too mangled, and I'd like to replace it. Finding just the hairspring (the rest of the balance assembly is good) seems to be nearly impossible. Unfortunately, finding the complete balance is also a tough one. Ofrei says they can't get it, and Borel has it backordered, but I fear it may never come in. The part is 721/2043 for complete balance. Do any of you know of a workaround or good solution to finding a part for this cal 730? It's a 21,600 bph. I'd prefer just to have the hairspring and not waste the rest of the balance.
