[BC] Nautel 2 Armstrong

[Milton R. Holladay Jr.]

`The problem was not the insertion of the tube, but the removal of the tube
from the plate cylinder/column, which was extremely tight. I've seen a
puller that would remove a tube from above, like a CCA, but not from below.
I've never seen a puller in an Eimac catalogue, though.
I must be mis-remembering something about the phoning, but I had to wait for
callback.
