The carbine at the bottom is a Modello 1891 "Carcano" cavalry carbine.
Unfortunately, the folding bayonet has been discarded, bayonet pivot ground off and butt plate replaced with rubber pad. The "sporterizing" or "bubba-izing" has substantially reduced its value to less than $150.
The rubber pad on the 98K destroys its collector value. It is worth no more than $400 as a shooter.
