Thats a good question, but since 1932 all bayonets S84/98 and other used in Army were blued, so this was blued too, when a rust on spine, there is a reason why someone polished the surface to clean the light rust.On spine should be date and proof, Weimar eagle over 61(49) or Su25 b.r.Andy
Other proofs should be on ball finial, guard and pommel and under grips.
As You could see the pommel and guard same as scabbard has remains of blueing, the WuK on blade would be not dark when not blued, same as in fullers are remains of rust and blueing that was cleaned, even it was done well and mashinelly.
