machine gun oil cans? What are these?

[Tino]

I would like to identify these oil cans.
Does anyone know what these cans are and where they were used for?

I was told they were WWII machine gun oil cans.
What are the markings and why do they have 2 seperate compartments?

Thanks,
Tino

typical russian style oilers. 1 and 3 are cyrillic, letters are 'sh' and 'n', middle is chinese copy. solvent and lubrication... a little research should turn up those russian words.

Mosin Nagant oilers. Sh - Shеlochnoe, N - Neft /cleaning solution, oil, but have heard also N means Neutral/

The Chinese one says grease on the left and oil on the right
