Hello Marcel,
Thanks for the reply,
Sorry to say that the online CWGC site does not (as yet) list the Unknowns. Reason is perhaps it is that they are unknown. I would say that it would be a help to researchers if their plot numbers were listed along with arm of service, such as Army or Air force that is if it is known, and a date .
I think that the answer may well be found if you follow the guidance that Hans gave in his post.

Good hunting,
Alex
