A really unusual set of 5 mid Victorian Gibbons antique geared winders, either for roof lights or transom windows. The key fits in the front and rotates the 7mm square socket on the top that would have connected the roof light or transom window. They've had a bit of a clean and a light polish.
Sold as a set of five with one key.
Condition:
Some weathering and a few marks and scratches.
