There's filling holes, then there's just plain inconsequential....
Do 17Z-2 - obsolete before BOB, already being withdrawn, small % in BOB bomber force, after that none.
P.Z.L. P.11
P.Z.L. P.37 Los B
P..Z.L. P.23b
You want 3 1930s designs that are fairly obsolete by the time the war starts, that only took a very small part in the Polish invasion, and fought in extremely small numbers?
Why not include the Stearman biplane? It had about as much impact on the war as these 3 did.
Ca 310 Libeccio
Do you even know the planes you're requesting? This is a plane that had such bad performance during the Spanish Civil War, it wasn't suitable for WW2 use. Quick paste from wikipedia: "The Ca.310 was not considered an effective combat aircraft and when it saw service during World War II, it was as a reconnaissance aircraft and as a light bomber in areas where no serious opposition was expected"
Gloster Gladiator Mk II - maybe a small hole, but pushed out of service at the beginning stage of the war
Gloster Gauntlet - 1935 plane, obsolete, only 1 squadron in the early weeks of the war, "The last use of Gauntlets in UK was for meteorological observations and the last such flight made by a Gauntlet were carried out on 6 December 1939 by K5280 of the Aldergrove Meteorological Flight."
I'm just gonna stop here. Dude, you're asking for every obscure plane for no reason, regardless of the (lack of) impact they had on the war.
