I bought this Vigilant on FB Marketplace in the Fall. He wasn't a 'stove guy' and didn't know much about the stove, only that he bought it and it was oversized for the room he was heating with it, so that's why it was for sale. It needed all new gaskets, and some work on the damper, which I didn't have much difficulty with. However, it has this weird pulley type contraption on the front of it. It's broken and doesn't move or appear to be connected to anything internally. I downloaded the manuals from VC online, and none of them reference this device on the stove. Just wondering if anyone can share any input about what it might've been used for? Also, any way to semi-accurately date this stove? Thanks so much in advance for any insight!
