They're in pretty rough condition. The plane iron (blade) looks like it's been used as a chisel -- the upper end is mushroomed a bit from hammering.
I searched for that "BLACK-DIAMOND" logo and came up empty. The name 'Black Diamond' is in use here and there, but not with that logo. I guess the BLACK-DIAMOND outfit that once made planes is no longer with us.
I have a retired 2" plane iron that dwells in the bottom of a tool box. These two items can join it, like so.
There, they even have a slipcase now; they can't complain about the accommodation.
