These are not Ti, they are anodised aluminium. they are incredibly light but rather flexible callipers I think weighing in at around 200g each. They were supplied with the standard late type CLB levers and aluminium outer cable which helped reduce the weight of the set still further. They were reasonanably common in the UK in the late 70s, early 80s. I think they were known as CLB Professional but I would not be certain until I checked.
