Original Item: Every now and then something shows up that we thought we’d never see. The official nomenclature for this scarce brush is BRUSH, CLEANING, STEN & THOMPSON MAGAZINES, MK I. The British Ordnance part number is B3/BC 13A.

The assembly consists of a bristle brush about 1-inch in diameter attached to a fiber cord about 36 inches long. A lead weight is crimped onto the far end of the cord. The cord is attached to the brush loop with traditional whipping. We have very few of these original magazine cleaning brushes. Most look to be unissued.
