Thanks chaps for the info on the bolt in lieu of the drain tap. I had thought of doing that but wanted to keep it original if possible. Now I learn the bolt is in fact original. Would anyone know the thread type necessary ? Also are parts books available or an owner’s manual. My understanding is that there never was an owner’s manual even when purchased new. I find that quite odd. Weird even. Whatever the case many thanks once again for the input.
