WIW Vintage Offenhauser Alum 4bbl manifold

Thanks all for input, was just given to me recently so haven’t had it apart. It just looks to clean to me to have been in service, if something is being hidden don’t know. I’ll do some more research on this relic and see what turns up. I probably won’t use it, since I prefer the Super Six set up I’m running presently. But it was good to get some feedback chatter on it.
