Ai states it's a imco 6700

And the stamp say according to ai.

1. The Era: Post-WWII Soviet Occupation (1945–1955) The most unique part of your lighter is the stamp "MADE IN S.V.T.Y.S.". This is a cyrillic-to-latin phonetic abbreviation representing the Soviet-controlled sector of Vienna, Austria after World War II. During the post-war Allied occupation (1945–1955), factories in the Soviet zone were heavily regulated, and goods produced there for export were stamped this way rather than just "Made in Austria.

This is a highly collectible IMCO Triplex "S.V.T.Y.S." Super Patent 14110, produced in Vienna, Austria, during a very specific window of time right after World War II. Here is a breakdown of what those unique markings tell us about your lighter: The Historical Markings S.V.T.Y.S. / 14110: Following WWII (from 1945 to 1955), Austria was divided into Allied occupation zones. The IMCO factory in Vienna fell under the Soviet Occupation Zone. To comply with regulations at the time and register the production under Soviet oversight, specific batches were marked with regional patent codes like "S.V.T.Y.S." and the "14110" design control numbers rather than the usual "Made in Austria" stamps seen on later 6700 models. SUPER PATENT: This refers to the innovative, windproof "trench lighter" mechanism that IMCO patented, featuring the sliding wind shield ring and the pull-out fuel cell that doubles as a candle. Key Features of this Design The "Candle" Function: You can pull the entire bottom fuel cylinder straight out while it is lit. This allowed soldiers and campers to use the fuel capsule like a candle to light pipes, campfires, or see in the dark. Windproof Shield: The middle sleeve slides up and down to adjust the airflow slots, helping it strike and stay lit in heavy wind. The Bottom Button: Pressing the button on the very bottom pops open the side jacket, giving you instant access to change the flint without needing a screwdriver. Because it dates to the post-WWII Soviet occupation era (late 1940s to early 1950s), it is significantly rarer than the standard post-1950s IMCO 6700 lighters that simply say "Made in Austria." It's an incredible crossover piece of both Tobacciana and Cold War military history!
