Hi brought a old ground dug Mills as it had this strange lump ? bit going through it , it was covered in rust and dirt but when brushed and cleaned could see it was like a copper piece through one side and out the inside , at some point someone had cut one side out to remove inners ? i presume as the lead plug base is stuck tight . the cut was not done with anything electrical as its a bad cut , not smooth anywhere but must have been done along time ago as it was very old rust all around it . I have searched the web and cannot find any mills with this lug? on the side does anyone know what it is or could be for ? . cheers
