The foam insert has deteriorated and as such the case will need some elbow grease to clean. As far as I can tell, the knives have very little if any usage. They have been sitting for a long time and some oxidation has occurred but no rusting or pitting.
I think a good cleaning of the cases and blades themselves will bring the set up to a 95% condition. The handles appear to be a reddish brown micarta.
