Need Help identifying ACS bayonet

[Reichspicker]

Hi to all,

I need your opinion about this two bayonets (One Horster K98 (seems original to me) and the short ACS (Alcoso) bayonet).

Are those original?

What can you say about the ACS one? Which unit used this short blade? is it from ww1 or ww2 era?

Regards and thanks...

Both authentic, of similiar age pre-World War 1 to early 1920's range. The larger one is a KS98 dress bayonet, the Alexander Coppel knife is a trench knife/fighting knife. This style of bird head pommel often had a non functioning button that gives the appearance of a bayonet, but it not functional as one.

Nice bayonets question are the frogs, i assume the one brown frog looks like turkish or different dress type version.
ACS looks like WW1 period Officer Sidearm KS98 non attachable on rifle, the blade is typical for Grabendolch versions, handle should be probably magnetic for steel one.
Hoerster is a attachable version of KS98 bayonet, it was nickeled i assume its too steel handle, also magnetic.

Thank you both Anderson and AndyB for your replies.
