Help me ID these wheels

Carefully remove the trim ring, near the valve stem there is a part number, if the number ends in “390” you have some rare factory original 1970 15x7 Rallye wheels! I’d they are 15x7 those factory trim rings are also very rare, both are worth good money….just seen a 15x7 390 wheel for $500 each…even if the trim rings have damage they can be restored. NOBODY makes correct trim rings or wheels, all the repop stuff is not correct…I know some people will say “big deal” but it’s a big deal to people restoring the muscle cars and they are always looking for correct stuff. I sold a correct 15x7 trim ring on eBay for $200 and it was not prefect, but still nice. If not 15x7 they could be 15x6.5, more common but also getting harder to find.
