I have a photograph showing stores and equipment being offloaded from SS Umona (probably) in July 1917 at Archangel, see attachment. The detail shows the writing on the crates, and includes the designation P.N.Y.O. Any offers on what the Y stands for.
Usually it is T for Principal Naval Transport Officer, which would seem appropriate in this instance. They were supplies to the Armoured Car Division fighting on the Galician Front at that time

It certainly looks likely that PNYO should have been PNTO.

Despite extensive online searches I have not been able to find any reference to the PNYO designation and come to the same conclusion as Alistair that it was an error in the stencil make-up and that it should have read PNTO.

Thank you both - I can see no other plausible explanation, but will keep an eye out for PNYO
