How long does Ferric Oxalate Solution last?

I bought a Palladium kit from B&S back in 1996(!) and made a few very small prints from medium format negs, but life got in way: marriage, two moves, three kids, full time commercial photography career. So I am guessing that the #3 solution, the Palladium, is go to go, but what about the Ferric Oxalate Solutions #1 and #2?

If the Pd is still good, I may just sell it on the list and use the proceeds to finance a new DA timer.

I've not heard that palladium goes off, but the ferric oxalate isn't supposed to last more than 6 months. I've had it stop working for me, though I think it was more like 8-9 months. My current batch was mixed in April and still working OK, but I'm almost at the end of it.

Yours is over a decade old? It's toast.
