Speaker identification help

hi everyone! I recently picked up a couple pairs of speakers that have no identification on them at all. The speakers a vintage for sure, very heavy, and seem to be made of solid wood. The woofer surrounds are inverted and doped. The front edges of the cabinets are beveled. The guy I got them from stated “I think the name is pinna audio”, and I don’t know if I am spelling the name correctly, but I can not find that company anywhere. I need to identify these so I can try to replace the paper tweeters which have deteriorated. Please see attached pictures. Thank you.

 

A wild stab in the dark but I have a dim recollection of a European company called something like ‘Pinna (Pinea?) Zigmahorn who sold kit speakers. The ones you have do look like they’ve been assembled at home.

 

Thank you for the info, I didn't even think of the possibility of them being a kit! ill start focusing my research on vintage kits and see what I can dig up.
