The frontpiece (also known as shield or badge) of firefighting helmets has been a distinctive part of the American firefighter’s helmet since it was developed by Henry Gratacap in the early 19th century. These frontpieces displayed a variety of information. The fire company's name and number appeared, often alongside the city or town where it was based. The frontpiece could also include the owner's initials and rank. Most fire helmets had leather frontpieces, but frontpieces could also be made of metal, especially on presentation helmets or those worn in parades.
This leather frontpiece was made during the 19th century. The frontpiece has raised white leather letters in banners at the top and bottom of the piece that reads “AGILE/JJK.” A recessed number 6 is in the center of the piece, and three silver stars arc above the word “AGILE.”
