Mechanism
I should also say it has a mechanism I haven't seen before, which is that the shuttle is mounted onto a horizontal bar and as the shaft rotates there's an arm that slides the shuttle back and forth along the bar. It doesn't swing in an arc like the other shuttle machines I've seen. I'm presuming it's either a machine designed for travel, or a child's machine. Instinctively I'd say it's more modern than it looks, just from the way the decals are applied and and the way the serial number has been etched onto the plate.
