When you first checked the dipstick the oil would have looked clear and golden .Had the oilpan been made of plexiglass you would have seen the bottom layer would have been black goo and under that water. Over decades in storage engines are condensation factories as yearly temperature changes the condensate water lands up in the very bottom of the oilpan . The oil pump pickup is sitting in this cocktail it has a fine screen around it . When you start the engine most likely the screen becomes partially blocked or even completely blocked .The cylinders and connecting rods are lubricated by oil flung up from the dipper tray could be in your case the noise you hear could be the pistons going up and down with insufficent lubrication . The oilpump supplies oil to the dipper tray,camshaft and valve chest where gravity feeds the main bearings through the three holes .Sadly many engines that have been in long term inactivity have been damaged by starting without a thorough engine internal clean . That golden oil on the dipstick is the killer .

John in lockdown still in Suffolk County England .
