Rare WW2 Matching Makers and Dates German M24 Stick Grenade

Rarely encounter a WW2 German M24 stick grenade with matching makers and dates to both handle and canister. Both are stamped with the date code 42 = 1942 and maker code "brb" = Richard Rinker GmbH, Menden, Kreis Iserlohn. Incredibly the screw on cap still retains the spring and paper washer, and the canister has remnants of the original factory ink stampings.
