This might fit

The sash cramps look quite old and are of an unusual length.

an interesting shot.

Thanks for the comment. This stall in the Saturday Market at Saffron Walden has a huge collection of old tools. Many rusty spanners, bent screwdrivers, damaged garden forks but also a load of old collectable items like moulding planes that always have a few elderly enthusiasts hanging around. A great place to try and find that 17/32 Whitworth ring spanner that you really need
