When did PNP start using the term comrades?

[Tropicana]

As mentioned I am connected to one of the founding fathers and his daughter never heard him use the term comrades.

[Wahalla]

from Norman times... The 4 H's used it.I am sure Norman used it in one or three speeches.. i heard Edna used.. it was in common usage in 1969 after Vivian Blake lost the leadership bid...... since u are only 35 from before u were born.....
