There are several possibilities as to what the specimen is including: 1) A form of concretion 2) The origins would be the infilling of surface circular dissolution cavities in limestone. The feature is very similar to the 'sandstone infill pipes on Carboniferous limestones at Trwyn Dwlban, Anglesey. 3) The conjecture for Furness is perhaps that it is a form of small or embryonic 'sop' of haematite. There are haematite sops very close to Moat Scar.
