The Bulgarians also produced a single spout metal oil bottle, the one pictured on the right is an example of one of these, I am informed.
I enquired with a colleague, a Bulgarian who deals/works in arms business, if Bulgaria ever produced either a rectangular bottle or double spout round one, with different letters on them, keeping mind that both Russia and Bulgaria use the same Cyrillic alphabet with only slight differences. He had told me he had thousands of oil bottles, both Russian and Bulgarian, so I asked him “What is the difference between Russian and Bulgarian oil bottles, different letters?” He replied “They look the same; we pulled them out of different crates, some with Bulgarian, some with Soviet AK’s”. He also told me “the letters mean alkaline & oil”.
