I have other vintage electronics and meters.  I will combine shipping. 

Here is a vintage model 640 Superior brand Industrial Analyzer meter.  I could not find much info on this piece.   The cables are there as well as the instructions!   The alligator clip wires are very stiff and may crack when moved, so I did not mess with those.  The others were flexible enough to move and picture.  I did not even plug this in to test it.   I'm selling it as you see it.  I didn't want to risk damage by plugging it in with the loose wires inside (see pics).  The case is in good shape with dovetail corners.  I've never seen a setup where you can use external battery power like this one (cables are also included!!).  The last 2 pics show the label that was on the original box.  The box was destroyed, but I took a pic of the label that has the date of 1953.   Please see pics for more details.   

******SOME STATES ARE NOW CHARGING SALES TAX ON PURCHASES.  I THINK IT'S BS AND WRONG, BUT EBAY DOES IT AUTOMATICALLY.  I HAVE NO CONTROL OVER IT.   VOTE TO CHANGE THINGS!

*****BE SURE TO CHECK THE SHIPPING TAB!  THE SHIPPING SHOWN MAY NOT BE THE CHEAPEST.  I USUALLY HAVE DIFFERENT CHOICES. 

****** INTERNATIONAL BIDDERS: I USE THE INTERNATIONAL GLOBAL SHIPPING PROGRAM. CLICK ON THE SHIPPING TAB AND SELECT YOUR COUNTRY.  IT SHOULD SHOW YOU THE SHIPPING COSTS.  IF YOUR COUNTRY IS NOT SHOWN, THEN I WILL NOT SHIP THERE!  I DO NOT MAKE THE IMPORT COSTS AND SHIPPING COSTS.  THE EBAY SHIPPING CENTER DOES.  BUYER WILL BE RESPONSIBLE FOR ANY AND ALL IMPORT COSTS. 

RETURNS: I will accept 'free' returns ONLY if the item is not as described.  IF you don't like it, doesn't fit, changed mind, etc, there MAY be a deduction in the refund to repay the return shipping I am charged.   Original shipping is NOT refundable for any reason.  PLEASE understand this, especially if you are buying something that costs a lot of money to ship because you will not get that original shipping refunded and I may deduct return shipping fees (figured on a case by case basis).   Thank you.

**** I RESERVE THE RIGHT TO CHANGE SHIPPING CARRIERS AS LONG AS THE PACKAGE WILL ARRIVE AT THE SAME TIME, OR EARLIER, THAN WHAT THE  BUYER CHOSE.
