Hello again everyone, I posted yesterday about my great grandfathers tool box that was passed down to me. Well I have been told it is a KRA-250, a KR-24 and a FB-50 Ferret box. Anyone out there have this same tool box. After hours of research I found 2 boxes that looked like they were the same on as mine, the only problem is they were ebay ads and the sellers didn't know what model they were either! This box has no model #, just MADE IN USA on back. There is a pull out tray, leather handle and a little compartment in the right bottom corner...Here's pictures again, thanks everyone!
