Bought an antique today, wooden bar about 1.5 inches in diameter, maybe 15"-18" long, square on one end with a yoke attached to a pivot a few inches from the end maybe 3" long and with cloth on the end, labeled "Pullman window jack". Presumably used to open windows, perhaps to hold them open. But I can find nothing online to show me a picture of one to tell if it's a legit railroad item or what. Any ideas?
