This section includes photographic illustrations and / or information regarding the manufacturer codes and hallmarks seen on various types of U.S. military insignia. - All currently certified contractors who have been assigned a manufacturer’s hallmark code have been included.

Understanding the Context

However, a number of those do not make metal emblems and they are flagged with their specialty (textile, decal, bullion, plaque). See the code list for more detail. IRA Green Insignia maufacturing goes back to 1943. As far as I know they used the hallmark 3G in the 1950's and later used G23 in the 1960's and later.

Key Insights

During the Vietnam era G23 would be correct. They did make sterling badges up until the mid 1960's when they switched to 1/20th Silver Filled. Current badges have no silver content. Does anyone know the time period that Lordship Industries/Products used the hallmark "Lordship NY-GI"?????? I believe it to be sometime in the 1980's.

Final Thoughts

Thanks for the help! Mark sends Obsolete officer's gold UDT badge with seldom seen hallmark By Tonomachi, in BADGES, AWARDS, DUI, AND COLLAR BRASS Recently picked up this pair of what I believe are WWII era Naval Aviator wings but I have never seen the hallmark "FSS". Also marked Sterling with a drop in pin fastener. Well made wings. Anyone seen this bird. I posted it a few days ago on a WWII hallmark thread but got no response so am postin...

Their hallmark was an upright sign post with an arrow pointing east and a sign with a bell hanging from the arrow. To answer your question about Bell Jump wings being made or issued during WWII, I do not know. I know through previous threads there has been ongoing questions surrounding the authenticity and legitimacy of LG Balfour wings that also have an "S" struck below the LGB hallmark. Back in the mid-90's I was able to purchase two complete salesman sample cases of Balfour insignia which came directly from the son of a Balfour salesman who worked for Balfour during WW2 and beyond.
