Rechkalov's first P-39
 

Years ago Massimo surmised that Rechkalov flew D-2 SN 138547 in April 1943, but the fuselage number was unknown.
Recently I became aware of a decal set for P-39D-2's from Colibri which states Rechkalov flew SN 138555 white 27 on 9 April 1943.
Is there any new information which supports Colibri's claim? Could it be this is the aircraft he flew through early-mid April 1943? It appears Nikolay Iskrin may have flown it from 15 April, registering several kills from that date.
Thanks
Peter
