7.62x39 help needed

I received a letter from a non-IAA member requesting information on a 7.62x39 steel case with headstamp 23 (12o’clock) and 74 (6 o’clock).
He has a sealed tine of 660 rounds full of 20 round boxes.

On the tin is printed:

7.62 PS7.GS% s-23
43 M 660 DB 74-111
KARB. 84-[7] VUFL 12/73 51

Questions:
Country of origin?
Steel core?
Corrosive?
Year of manufacture?
Factory where made?
How did it get here, Macon, GA, USA?
Other info? Value?

Thanks for any help that I can relay to the requestor.

Gary,

it is a Hungarian can, basically the printed information is

first line:
7,62 (calibre) PS (steel case ball) GS (steel case (I’d expect lacquered)) 23 (maker of the cartridges)
second line:
43 M (model 43) 660 DB (660 ea.) 74-111 (lot 111 of 1974)
third line:
KARB. 84-[7] (I don’t know) VUFL (powder type VUFL) 12/73 51 (lot/year code of powder maker)

Country of origin? Hungary
Steel core? Yes
Corrosive? Yes
Year of manufacture? 1974
Factory where made? Matravid

Hans,
Thanks for the very quick and helpful information. I will relay the info to the requestor. I do not have the can to capture an image unfortunately.

Maybe he can?

I stumbled across this thread while trying to figure out my own spam can, which I now know is identical to this gentleman’s. Here’s a pic of mine:
