Pre-war, (and pre-Tolex) Browning cases were black or dark brown leather and imitation leather covered cases with fitted felt covered interior. The real leather case was the Model A, the leatherette was the Model B, both for automatics and the Models S and SB for the Superposed. They may have been available until the introduction of the Tolex in the 50s, but for a certain period of time, no cases were mentioned in the catalogs possibly indicating that the pre-war cases were no longer available. These early cases are relatively easy to identify is the brass logo plate is intact. The interiors will identify them also because, if original, nothing much will fit in them except the gun they were designed for.
