Sorry. I got to thinking later that maybe I should have included that info with the OP.
As of this reply, looking at the post, it looks like still available.
$475, unwilling to ship, in Ashland City, TN.
And since then, another pair has been posted, in Nashville, $425 for a pair of '79 H 1's. Posted in the same FB Audio Trader for Audiophiles group.
N/a with either post or seller.
