Field Mail stamp?

[deValcourt]

Ya don't see stuff like that too often. Where'd ya find that Phil?

Here's another one I found on the auction site. It is made by the same manufacturer as the one I posted before. The seller does not say anything about it being a "post mark," but after all of the above, I'm inclined to think it is. It also has that unusual two-thirds of an infinity symbol - for lack of a better description - below the numbers, which is similar to the "horn" in the Russian symbol for the postal service. There are also fewer numbers. It could still be a date stamp if only the last two digits of the year were used.

All the seller says is that it is a "Soviet seal 1967: Factory city Permi "Promsviaz" - inscription on seal Breskiy region city Baranovichi."
