damned complicated, guess I will be way of with all answers this time.
Anyhow.

#388: Gauge for comparing silver(gold?)-content.
#389: blind-riveting gun (no!) or air operated hammer for sheet metal
work (also wrong)
#390: sinter metal filter. Don't ask where it was in!
#391: airless deep diving shoes. Maffia style
#392: radio knob screw on tool. The inventor was without success,
because the knobs are slipped onto the axle.
No really, this ain't a commercial tool. Someone built it for his own
purpose. Maybe to unscrew (Australian style) bottle caps.
#393: for straw cutting.
