This guy is awesome...from a time when men were steel and ships were wood.

Thanks for the series!

Man I wish he had some real long videos!

Great vid i like it.Greetings from Poland

For more on US WWII military signal mirrors, put this search string into Google: "WWII emergency signal mirror" to find the photoillustrated article at the usmilitaria site. Over 1,000,000 of the plate glass mirrors shown here were issued in WWII, and used by Canadian and Australian forces as well as US. The metal mirror with a tethered aimer is the WWII British issue type, which came in 2"x2" (shown here) and 4"x4". Put the search string: "dinghy heliograph" in Google for an annotated photo.

I believe those were destroyed because it glowed because of radium paint which is very radio active if you got a speck of paint in you lungs that's it.jim

Wonder how that would compare with a fragile CD?

F the vid. I want that hat.
