Polish gasoline iron

Andrzej gives me a Polish gasoline iron (actually a trade, I will send him something interesting from the US when I return).  The iron is shown here on the counter in my apartment, and Kate took a picture with “my” and “her” irons for comparison.   This is quite large at 38 cm (15 inches) long, with a large bronze gasoline tank.  I am guessing maybe 1920s.
