Not police, but a private purchase Kurzes sawback or ks98 from the imperial period. It has 2 rivets instead of 3 which is typical of Anton Wingen during that period. Most likely purchased by, or for, an NCO. Sawbacks on dress bayonets at that time usually denoted the rank of NCO.
Again hard to judge value by these pictures, but usually in the $250-$400 range.
Thank You, That's helps a lot, it is in very nice condition, I will work out the problem with my camera this week
