fighters in "minor" countries

[Tzaw1]

Bulgarian Bf 109E's were in antiaircraft defence, inter alia at Black Sea coast. So they were in operational use, but it seems, that they din't see combat.
Avia B.135 only combat mission took place 30 March 1944. The one patrol of four Avia's took off against massive USAAF's bombing raid over Sofia.

I believe this were Avia B.534s. I know Bulgarians used them operationally.

looking on 135 i found the fightning of the 30 march 1944 but they are trainer, were planes of flight school...

Yes, Bulgarians used B.534's operationally and B.135 only in Flight School in Dolna Mitropolja.
But this was the only case of operational use of B.135's. In detail this is described in Avia B-35/B-135 monography by Miroslav Bily, Denes Bernard and Pavel Kucera.

For Croatia I found MC 200 in Kroat. JGr1 too.


EDIT
For France it is necessary to add Yak-1, -9D, -3
For Poland: Yak-1, -3, -9, MS 406, Caudron CR-714, D.520, H-75, Bloch MB-152, Koolhoven FK-58A, Mustang Mk. IV
For Czechoslovakia: La-5, -7,
