Stroke with only Pistons and Crank?

Don't mean to sidetrack (well, yes, I guess I do) but how much is Mallory these days? I have a cracked fuel crank with eight slugs of various sizes, wondering if it's worth my time to dig them out.
Do it.
Ask the machinist if you were to bring them in if he could use them. I'd say they can drill to any size so yes.
