E&H Research Generation 70 G720 Mos Driver G70A-2 Probe & Manual. See the last pic for an example of what it's for. The listing is for the probe & manual only.
From the inventory of
a closed aerospace business. Untested, as I don't know what these are
for, let alone how one would test them. So, sold as-is. But, so far, everything
from this place has worked. Free shipping in the US.
