Found on a short walk this afternoon. I've no idea what the round things are but the rusted out Silkolene can caught my eye.

Silkolene (now FUCHS Silkolene) started out as Dalton and Company in 1908 and initially focused on manufacturing veterinary products for local farmers but later established a refining service for used aero-engine oils (hence the Concorde emblem).

Silkolene is a brand I'm very familiar with as they were based in the nearby mill town of Belper, Derbyshire.
