you rule ! thanks a lot

Hi guys ive recently inherited 12ks of lego, amongst them was the following part, ive trawled through various sites but i dont see it listed or pictured anywhere. its from the pat pend era so i cant look up a part number unfortunately. This part is very heavy at the cylinder bit, seem like it could be a counterweight or something of that ilk. hopefully someone out there can recognise it ! thanks !
