Here we have a wonderful and vintage WESTERN UNION TELETYPE MACHINE 28-ASR. I am clearing out a family estate and this treasure was tucked away. I am not sure when it last worked. I plugged it in after dusting it off a bit and clearing cobwebs. It turned on but on the advice of some collectors they suggested not putting it through any of its paces without a thorough cleaning and lubrication. I do not see anything that is supposed to be there mi...ssing based on photos and other images i compared it to in my research to find out just what it is. I took photos of the model/maker/serial plates as that may be pertinent to determining an exact model or age to this piece. Happy to receive and add any additional information that you may be willing to provide. This item is available for local pick up in southern california or i can open the door for the shipper or mover of your choice at your cost. See photos to answer most questions and make aninformed decision before making a bid or offer and ask what you need and Iwill try to provide answers about the product. Proceeds fromthis and all other ebay sales help to supplement my science classroom purchasesof materials and equipment. Thank a teacher and shopgenerously and let your friends know about ebayseller esteem1. Whileprices are very competitive they are still mostly negotiable as some funds beatno funds for my class.
