WWII or earlier german made k98 bayonet made for export most likely to Spain or Portugal only marked 664 on both sides of the tang. Wood grips are secured with two steel rivets.

Originally, this was one of the S84/98 III bayonets that were sent to Spain for filling the first contract that Germany had with Spain for bayonets in the early 30s. The script “O” on the bottom of blade ricasso denotes it as such. Coming from the factory it was finished in the white (no bluing), devoid of all stamps and marks, except for the script “O” and there was no flash guard. The original scabbard issued with this bayonet would have been identical to one that was issued with an S84/98 III, except devoid of all stamps and marks. The grips look to be homemade replacements. The blade is in very good condition considering these bayonet were really used and abused by the Spanish army, usually sharpened to heck and rusty. Thanks you know who you are.
