Radiator Drain on a 1936 120?

I am currently helping a friend with his 1936 Packard Dietrich Convertible Sedan. It's been in his family since 1937, although he's never personally laid a wrench on it. Hence, I'm the one getting a few things like a new head gasket done. Trouble is, I cannot locate either a radiator or a block coolant drain. He's only got the original handbook and has no service manual. I thought it would be an elementary "feel-around" task, but without the front end of the car raised, I can feel or see nothing that resembles a drain petcock. I did attempt to use the PI Manuals, but came up dry with that, too.

Secondly, does anyone recommend using products like Permatex Copper Head Gasket spray on the new 282 head gasket? There were no instructions that came with the new (Kanter) gasket, so I'm wondering if dry is best for a laminated gasket.
