All About Pocket Knives

Hi & Thanks before hand. Picked up this Presto looks like it's missing the swing guard . If so does anyone have a replacement and can install it .
Story of the Knife the guy I got it from said his father in law carried it in Burma while in world war 2 . I would like to get it original .

Very cool find.

Sorry to be so late to the party but I saw a set of guards offered up on eBay just today or yesterday.
