Nice Vintage Sencore TC154 Mighty Mite VI Tube Tester

Up for bid is this Nice Vintage Sencore TC154 Mighty Mite VI Tube Tester.  This was down in the furnace room of my family house sitting on a shelf for over 20 years!  I don't know much about this item but once you open the attached book with the settings to use for each bulb is a no brainer.  I ran tests on 6 different bulbs and it seemed to work okay but did not  understand about the Short test setting.  The case measures 10 1/2" by 10 1/4" by 4 1/4".  Insurance is included in the shipping and handling.  

Please contact me immediately if your intended Feedback is less than Positive!  I have been selling on Ebay for over 6 years now and I have impecable feedback because I try to give a fair representation on everything I sell even mentioning small flaws, nicks, scratches or anything that I notice prior to placing for auction plus providing a fair amount of pictures. Also, I mail out fast, guaranteed shipping the next postal business day after receipt of payment.  If, when you receive your item, you feel that I grossly misrepresented the item, I will accept returns. But, you must contact me within 24 hours of receiving the item. Shipping the item back will be at the buyer’s expense and, when received by me, I will issue a refund via Pay Pal for the purchased amount less shipping and handling costs.
