Found this.  Looks like he retired November 1956. Made Commander November 5, 1945.   I did see that in mid 1944, he was station at the submarine base in New London, Connecticut. The designator 2109 is a Medical Reserve officer that has retired.    

Looks like an authentic period example. I don't recall seeing a "BUYRITE" before which adds extra interest. Probably Japanese-made. Thanks for posting!

Looks like a great group. 

Sterling US military insignia is almost always marked "sterling".  But you really hit the jackpot.  You can turn your find into a regular  Ebay annuity payout of $25 a shot.

All look good to me too, nice patches AG

As part of a large assortment of US Militaria I picked up this week was a small box which had some weight to it and when I looked inside I noticed that there were Pinback Combat Medic Badges some still wrapped in tissue paper.  They're unmarked as to maker or content so I'll need to test them for silver but when I got them home and counted there is 100 of them.  The box was not from the manufacturer sadly as it was a recycled shaving kit packaging from the 40's but I'm still happy with this haul which I assume came from a PX or an Army Navy Store as they are NOS with many of them still wrapped up. I've come across patches in bulk before but never badges like these so figured I'd post them here.  

What happened to them?

Thanks guys🇺🇸✌️👍

OF Course.   LCDR is Lt Commander. MC is Medical Corps (that is the doctors) VS is the classification for Volunteer Reserve (Special Service)   Yes he was in during WWII I should have put the headings on the columns:   Date of Precedence is the date he got his currant rank. Year of Birth - Self explanatory Pay Entry Base Date is the date he signed in to the Navy. So he signed up on October 7, 1943 and was given his rank on October 12, 1943.   This entry came from the Naval Officer registry for 1944.    Haven't tacked him down for after WWII but may have stayed in the Reserves 

Great find,  It is in all probability an NY Militia plate from the Waar of 1812 or shortly after.  There was a lot of fighting in the Niagara to Buffalo part of the state.  Most off the Militia refused to go accross the river into Canada.
