Not too bad at all. Looking very nice.
As far as the a/c serial is concerned.. as memo serves ... Pierre Clostermann used three Tempest V kites with the JF_E code. One was of the NV724 serial ( quite well known ) Also the NV994. But there was probablt another one - the SN222. The NV724 is his post-war mount.
The list of Tempests flown by him...
The Tempest V : EJ 781, JJ-x ; NV 722, JJ-x ; EJ 893, JJ-W ; NV 942, JJ-x ; NV 722, JJ-x ; NV 971, JJ-x ; EJ 706, JJ-x ; NV 660, JJ-x (274 Sqn), EJ 708, US-W ; NV 728, US-X ; NV 927, US-Z ; NV 965, US-S ; EJ 804, US-M ; NV 970, US-O ; NV 987, US-R ; NV 667, US-A ; SN 131, US-P ; EJ 536, US-W ; NV 968, US-G ; NV 974, US-K (56 Sqn), NV 994, JF-E, SN 222, JF-x and post-war NV 724, JF-E.
