super six 1929

trumpet79

re my 1928 super six. I now have completed all the new top wood and installed a new vinyl roof. I used ash from wood I had sawn from my logs and white oak sawn from a tree from a friends back yard. i bought a juki commercial sewing machine to attack the interior later. this car has apparently been retrofitted with a later looking generator mounted on a pedestal in the left side of the engine. There seems to be a water pump on the right side connected to the bottom hose and a smaller group of pipe fittings connected to the right sid of the block with a couple if two eared flanges. Would this be where to drain the coolant? was this modification common? there is no apparent drain cock on this pump. Any ideas? thank you.
