Hi guys!
Can anyone help me with the tail numbers for the following flights? I have tried every website mentioned + Plane Finder. There are still 9 flights left:

2010-08-21 - W6578 - BOJ-WRO
2010-08-14 - W6577 - WRO-BOJ
2010-05-31 - FR8844 - BGY-WRO
2010-05-28 - FR8845 - WRO-BGY
2009-11-18 - FR9172 - GRO-WRO
2009-11-15 - FR9173 - WRO-GRO
2009-09-13 - FR8405 - STN-WRO
2009-09-11 - FR8404 - WRO-STN

2014-09-05 - K2887 - LUZ-WRO

The last one is probably the most tricky one - Eurolot (IATA: K2, ICAO: ELO) from Lublin to Wroclaw. The airline went bankrupt a few months after the flight.
I will be grateful for any help!
