Old Tajung Keris(es?)

@ rasdan :This is quite interesting, and enlightening. Outside and inside calipers. I adjusted a couple to more secure positions upon the wood screws on which they hung on the wall at work just this morning. My apologies for "thread necromancy" and, perhaps, irrelevant commentary. I was following a train of thought during the course of research, and it led me here.
Google Translator leads me to believe that "angkup randu" means something like "operator's manual for tweezers" or "hand-operated tweezers". Please don't feel obligated to reply. I'm sure the matter will sort itself out in time.
