Branson? Ultrasonic Swaging Or Staking Horn 51119DA3 New This item was purchased from a large business inventory reduction sale. This unit came in a box of items marked Branson. However, it does not have the brand name marked on it and so I am not able to verify the brand. I do not know the history of it. Many of the items from this purchase turned out to be items that were kept as spares. This unit has only very light scuffs that may be from storage or it may have been used and taken very well care of. It measures about overall 5 1/16" long and the tube is about 5/8" in diameter. I am not able to test it. It only comes with what is shown in the pictures. S548-23 d rl fdk 81002208
