Another (the same?) photograph of Hurricane HE-T has appeared on ebay:

Looking through this old thread, the general consensus was that it was likely to be either L2119 or L2121.
Interestingly, a look at ASN shows that codes have been allocated to these aircraft somewhere along the line:
L2119 UP-Z:
https://aviation-safety.net/wikibase/228325
L2121 UP-T:
https://aviation-safety.net/wikibase/228038
The reference to UP- codes is perhaps understandable, but I wonder where the individual codes came from? No codes are listed in the ORB.
Another problem is that neither of the "likely crash locations" is anywhere near the coast...
Can anyone add any more after all this time?
