AVIA Poland is easy to confuse with AVIA Czechoslovakia, which is a Skoda division.

-From the person in charge of the engine section at the Krakowie Museum, Piotr Lepalewski, the author has received additional information, which he considers of interest, and adds below.

-AVIA Poland has a different production line. If we make an index, we find the following:

-1924/29, the WZ-7 radial engine.

-1930, the WZ-100.

-1931/32, The Lorraine Dietrich LD-12Ed and 12b.

-1933, the Whirlwind J5B.

-1934, the P-4.

-1936, the “3” engine.

-1938, the Delfin 3T (Wright) and the G-R 7 (Mars 7) as the Mew.

-The company's main engineer was Wl. Zalewski, hence the WZ engines.

-He was trained between 1923 and 1926 at the School of Mechanics. In fact, in 1926, he designed the WZ-X1. He is awarded the WZ-18.

-And at the Technical Museum in Warsaw are other engines from this engineer. The X1 was called "Kogutek".

-Later XIIb became the "Kogutek II". Other exposed engines are the WZ-20, the WZ-25 and the WZ-40 (5-cylinder).

"WZ-100"

-The WZ-100 on behalf of the engineer Wl. Zalewskiego (Zalewski) was a 5-cylinder engine that gave 100 CV at 1,850 rpm and 85 CV at cruise speed.

"Avia P-4"

-The Avia P-4 gave 100 CV at 1,900 rpm and was designed by F. Peter in 1930.

-The Avia 3 was a joined design from F. Peter and Wicktor Narkiewicz (see). It is an inverted, four-cylinder, inline engine that was air cooled and gave 63 CV at 2,400 rpm.

"Avia 3"

-The other engine that is atributed to Avia is the Delfin 3T, which is from 1939, and which design is from A. Tupalski. It gave 280 CV at 2,300 rpm.

-Observe the long tube that passes outside the cylinders to drain the oil from the front.
