1980 Goodyear Polyglas GT E and F-70-14

Group,
I have had these tires since 1980 and they have been on my 69 Barracuda for a short time only. They have been stored in the basement so they are not damaged or cracked. They are still soft and look great. I had F70-14s on the rear and E70-14s on the front.
I never cleaned any of the white letters off until now since I ran them letters in. They still whiten up nicely.
This Charger in the photo is sporting the same ones.
Do any of you know if they came on any particular car when new?
Can you all think of anyone I should contact to see if they'd like them? I showed my local tire supplier but it is tough to find folks locally that can appreciate things this old, but more so, need them for an old car for just sitting around at shows.
I need to move them out of the basement and I know they are very old but I do not want to just waste them.
Suggestions?
