Badge to a friend of DOBROKHIM. Height (flag): 17.60 mm. Height (bayonet): 28.83 mm. Width: 31.88 mm. Screw length: 7.58 mm. Weight: 10.649 g. Made of solid silver and enamels. The reverse shows 3 silver hallmark stamps. The badge is in a great, above average condition with its details crisp and an appealing patina to the silver. The green enamels are mostly present and without repairs but does show a small chip in the upper left corner. There are also some surface scratches to the enamel (all pictured). Please note the absence of the screwplate. I’ve also included an ultra violet image to show the lack of modern repairs to the enamel. It also does a good job highlighting the surface condition. The Society of Friends of Chemical Defense and Chemical Industry (DOBROHIM) is a defense public organization formed on May 19th, 1924 in Moscow. The main task of DOBROKHIM was to assist the state in the development of the chemical industry, the chemicalization of agriculture, the deployment of the promotion of chemical knowledge among the population and its preparation for anti-chemical defense. In May 1925, the Society of Friends of the Air Fleet (ODVF) and the Society of Friends of Chemical Defense and Chemical Industry (DOBROHIM) merged into one Society – AVIAHIM of the USSR. We want to create a gas fence in which a new society will be built. Reach out to me with any and all questions you have. All sales are final. Condition and authentication are “as seen”.
Army Chemical Warfare Trophy. It’s also referenced as the Chemical Warfare Service Trophy, and was awarded to top marksman in short-lived competition that involved firing from 200 yards with their service-issued gas masks on in a timed event. This is one of the more striking, unique, and hands down rare badges issued by the Army… It was made by Bailey, Banks & Biddle of Philadelphia, PA and is marked twice with their makers marks and Bronze. It’s unknown how many were ever awarded in its short, eight-year lifespan, but it’s estimated less than 10 were awarded annually. It’s likely only a small handful exist over 90 years later, and this is only the second to surface for sale in the past decade. It’s a larger badge, and measures 2 1/8 across. It is guaranteed original, authentic, and in exceptional original condition as shown. This piece is a holy grail piece for many Competition Shooting Badge collectors, and is museum collection worthy. There are absolutely no issues with this badge… It’s uncleaned, the pin mechanism works, and the makers marks and details are sharp throughout.
