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 black leather frontpiece has two red banners at its top with raised white leather letting that reads “FRANKLIN/HOSE.” A large recessed white number “3” is in the center of the frontpiece, with white leather lettering below that originally read “BOSTON,” but some of the letters are now missing.
