Note the metal four legged stand with metal info plate used by MP troops to the left of the sand bag pit... you don't see that many around nowadays... Here's one from my collection and another one in use during embarkation for Normandy...  

Here is a Forum topic with a couple of pictures of the harness with the hardware attached.    

I kept these photos of a WW2 Merchant Marine jumper as well as a black and white period photo of two WW2 era Merchant Marine sailors wearing their jumpers.  However my father served in the Merchant Marines during WW2 and I remember him telling me that the only time he ever wore those jumpers was during the time he spent attending the US Maritime School at Saint Petersburg, Florida.      

So I recently got a PCU-15 including all rings and the fittings however, I have no idea how to assemble/put the fittings on the harness. Anyone that can help me?

I'm not really finding anybody by the name "Winslow Henkle" as far as medically related or even WWI related.  Sorry.  Perhaps someone else can find something.  There's a chance that Winslow was a middle name and he went by that but we would pretty much need to know his first name if that were the case.

Hi everyone, Is there any evidence of Merchant Marines wearing standardized or dress uniforms, similar to those seen in WWII?

Hello, I’m out of Oakland county, about an hour and a half away from Jackson.

I should clarify that the knife is stamped 2 - 71.  The sheath label reads April (probably 1971).

Thank you for this information and pictures , patches. This site has a wealth of knowledge. Thanks again
