They seem pretty beat up. Where can new ones be found?

It's an engine block coolant drain cock. If your local auto parts store can't help you, look up part # 8115 55/57 drain cock, ($5.95) at concoursparts.com. If yours opens and closes and doesn't leak, just clean it up (don't remove it). It looks like it either has grease/road grime caked on it or undercoating.

You can probably get them at your local hardware store. They are there for when you need to drain the block.

Ahh, gotcha. That makes sense.
I'll give them a good scrubbing, if they don't clean up or seem busted, I'll find those replacements.
Thanks guys!

Here's a better ideal for a drain plug.It's a marine item made by Mercury outboard. I replaced all my drain plugs, including the radiator, with them. You can even attach a hose to it. You can get it at a marine supply store, ebay. or Amazon. The last ones I bought were through ebay. Also see it under the Quicksilver brand

Part 8115 (Concours) does show an external nipple to which a hose could be attached. I will look at mine tomorrow to see if it also has the nipple (I can't remember if it does/doesn't). Having the nipple for attaching a hose would be convenient/less mess, but not a deal breaker. I would be more concerned about the drain cock leaking, if removed/replaced.

NPD has has the wing style in brass with attached sleeve for a hose - about $7. They work great and being able to attach a hose makes for a no mess job. https://www.npdlink.com/product/drain-cock-radiator-brass-14-inch-npt/135249/51491

Now we're talking. I think I'll grab a couple and replace these. I cleaned them up yesterday and they look pretty haggard. I'm assuming a little silicone when installing the new ones?

Here’s another style of drain petcock available in ¼” NPT. These are solid brass and available at the local hardware store and McMaster-Carr.

Those look more "period correct". How much were they?

It's probably one of the cheapest parts you'll ever buy for your car.
