Vintage Armstrong Quick Change Tool Post 81-009. From an estate sale so do not know too much about this piece, and how it is supposed to works. Check my PERFECT feedback, I dont cheat my buyers, it’s all upfront, no pur posely hidden faults with what I sell. I try to make all my buyers happy, by being upfront on my description of items and not having them receive an item that was misleading or not described for what it truly was. Please contact me first, so we can work out a fair resolution to the issue. Most of my items are marked, to avoid anyone trying to switch the item with another. Please be aware that this method often can take a long time to get to you, sometimes 6 weeks or more. IT IS THEN UP TO YOU TO CONTACT YOUR POST OFFICE FOR FURTHER INFORMATION ON HOW TO PROCEED. OFTEN YOUR POST OFFICE IS HOLDING THE ITEM AND SHOULD HAVE CONTACTED YOU, BUT ON OCCASION THEY MAY HAVE NOT. THESE SITUATIONS ARE YOUR RESPONSIBILITY AS I HAVE NO CONTROL.
