Thanks for the replies. Sounds like either bottle would be correct for the mid 70s. I have also seen the posters and noticed the 2 headed bottle, thats what got me thinking that perhaps the one I bought is incorrect. Last night I did manage to find a small paragraph in the book Kalashnikov Rifles and their variations by Joe Poyer.
It basically states that the earlier tin coated iron bottle had two compartments, one for lubricating oil and the other for a cleaning solution. Later types were the tin coated iron single compartment bottles for lubricating oil and cleaning solution. The latest style was the plastic bottles. The book goes on to show pictures of them all.
So to my understanding the Russians switched to a single compartment bottle sometime in the 70s that held a solution that cleaned and oiled? Or did they carry 2 of the bottles? I have my doubts that they would carry 2 separate bottles considering their magazine pouches only had 1 place to put an oil bottle. Im guessing around the time that they started to switch to the plum furniture on the AK-74 rifles that they also switched to the plastic single compartment oil bottles. I wander if there are plum colored oil bottles out there?
