Sorry to have to tell you this, but those metal can LM308s are no good.
Worse than that, they are at risk of ruining all your other parts through super scientific cross contamination, which is totally legit and not something I just made up 2 minutes ago.
Even worse, disposal of those contaminated parts is usually quite expensive.
But, since I think you're a good guy and I feel for your situation, I'll offer disposal services for those metal can LM308s free of charge.
I'll send you my address so you can ship them to me for proper disposal.
Q: Why is a drummer like a scud missile?
A: Both are offensive and inaccurate.
