Here are two certificates issued in the same year
on the same sextant, one by C. Plath, another
by Kelvin and Hughes.

I don't know what was the story behind this,
and why did the owner do this. (Maybe he dropped
his sextant on the floor in fall 1955:-)

I also have two certificates on my SNO, issued
with 1 month interval, one by Freiberger,
another by C+P, and I guarantee that I did not
drop my sextant on the floor in between:-)
and did not sail with it.
What C+P certificate says you can guess,
and Freiberger shows max arc error 0.2'.
I also have quite strong evidence (from my own star observations)
that both my certificates are a balooney.
