Very cool stuff Bentley, looks like most of it dates back to when tools were made to last, and (providing you took care of them) got proudly passed on from fathers to sons/daughters.
Danny, some things are irreplaceable and you've taken care of those; don't sweat the others, and don't kick yourself for what else/more you could've done. Things happen so fast you rarely have time to think rationally. If you'd got the pressure washer out, you could have electrocuted yourself if water came in contact with power, so count yourself lucky you were ok with just the hose!
