Play Hockey with old FPE! Save the newer ones for that temp before the panel change.
Larger or industrial go to re-manufacturer for a little $ each year.
Common ones (Murrey, GE, CH, SqD) go into a bottomless bucket and get used for temp power, or that need it now CB, but all eventually get the dumpster when the shop gets cleaned out. And every time it gets dumped, you walk back to the empty bucket and say, "I know there was one in there..." But if you save them forever you'll be knee deep in them.
