Nice ones!  I will repost your pictures if you want me to delete them let me know.

 

 

 
 
 
Yes these are most likely Philips N 6330, but manufactured for Philips by AKG so these are basically AKG K240 Sextetts ( or AKG 241 ??) in a slightly different housing. Very nice score there!
 
Hard to drive they should be 600 ohms.

I think Uher made some shells similar, but these I bet are the Philips ones you posted. They have a main speaker driver in the middle and 6 ( or 8 I forget ) passive round radiator holes around the outside of that. These act to tune the headphone.
 
Anyhow if you search in here for Philips N6330 or N 6330 something should show up.
 
Thanks for posting and welcome to head-fi. Be very careful in here, and " sorry about your wallet " as the standard greeting goes.
