Ernst Rohm Presentation SA Dagger…Haenel manufactured Lazy Man’s Partial Ground Rohm Presentation SA Dagger untouched as stored since the war…The brown stains appear to be hardened grease or cosmoline and I have left the blade uncleaned after testing a small spot on each side where the brown removed easily with simi-chrome polish, I’ll leave the cleaning decision to the buyer.(Ernst Rohm Presentation SA Dagger)
