I think the hats are a US Navy white summer cap for officers.
And my family gives me funny looks at what I bring home. If you know someone with a kiln that goes extremely hot over 1500 from what I just read on the internet you could probably put them in small graphite crucible and incinerate.
I've picked up several gold teeth over the last few years. Most of them are 16k.
How do you have them tested for 16 k? Or is the scratch just darker on the acid test kit?
Cap device is U.S. Army, not Navy. Navy caps are also slightly different in design. It is an officers cap. The dress whites are summer or "Tropical dress". It could also be worn with the "mess" dress. Army whites were optional and only required for officers and sergeant majors assigned to the tropics and southern US states.I think the hats are a US Navy white summer cap for officers.
