Years ago we stocked these as our skeletal bridge but I think Hammer Head is a far more apt name due to the shape of the saddles.

High quality chrome metal bridge, adjustable for height and intonation with string through the back of the bridge not through the guitar body. Supplied with mounting screws and solemn key for adjustment. The various key dimensions are shown in the photographs.

These are a nice slightly different  looking bridge to that found on typical hardtail and would great on your project or custom build.
