Please a last question:the badge is possible to know if came with the hat from origin(both together since WW2)??? Thanks once more 

For the 127th anniversary of the Battle of Manila Bay today, here is a cased Dewey Medal group in my collection, named to an Ordinary Seaman from the USS Boston. He was from Astoria, Oregon, and served in the local Life-Saving Service on the Columbia River for about 10 years after the navy. Articles are from the Astoria Daily Budget from 1898 and 1899.                    More views of the case.           

Congratulations 

This badge was made only late WWII...1944-45

It looks amazing Joe, thanks for sharing!

Thank you for the detail of the correct longtail M2 mount with fixed ammo box! This is a frequently missed detail for tracks

That type of nut on the back seems like a strictly WW2 device.

Three attempts to make the box and a pile of ruined lumber, but I think we got it.  My son, who did almost all the work on this, will write up some specifics if someone wants to build a box at least similar to the photos I have found.  We skipped the backing board element which would have been nice, but this was a major challenge to build as it was.   Dimensions are 10x6x9 with the front lip at 1 1/2 in, and the rear hinge at 5in at a 30 deg angle.  Cherry would look nice, but isn't as tough as oak, third iteration was oak.   The first box would not open with the clock in it, and had other flaws.  The second box we tried cutting angles after assembly and this didnt work at all.   The two critical elements are the box hinge open without colliding with the clock face, and that the two halves end up falling even when fully open so the clock has a stable base to rest on when in use.   I am sure a professional woodworker will find flaws.  I am more interested in sharing data with someone that can use it to get pointed in the right direction which is why I am posting this.  It will serve its purpose of protecting the clock in transit, which is the primary goal of it, and I think it looks fairly nice even if not perfectly matched to GI.  

Econo-lead, found on a myriad of cards without specifying maker names. I don't think firms particularly wanted their brand associated with such a shoddy product, even though they had little choice but to produce them to make demand.   Easily broken and quickly discarded when the Marine could find a suitable bronze replacement.
