They are similar varieties. Each came from a different source, both originated in Syria.
Salem Dark came from my uncle Salem who has been growing this syrian fig for many years and it's very vigorous and productive, and cold hardy.
Macool I collected from syrian fig grown by Mr. Macool. Tree had been at the property for at least 25 years, before that he got it from his father in law who had the fig for at least 30 years, and it was brought from Syria at some point.
Are you the same fig? there's a possibility, or they're just cousins.
