Regarding the Erma EL24 kit, Page 560 of the new Karabiner 98k book notes that "[a] few rare early kits were fitted with a special installation tool." The book also points out on page 563 that early kits were fitted with a cleaning guide tool. Are these talking about the same cleaning guide tool or was there some other type of installation tool issued with the very early conversion kits? Does anyone have a picture of what this tool might be?
