Hi Alan. Yep, i agree about the possible Covid malaise which seems to have descended upon the forum.
While i love a good guessing game i am afraid i would not want to say too much based upon what you have already identified as "very poor photos". I just can't see the details in this keris well enough to create any kind of an informed opinion.
Is the mendak upside down on this keris? I really can't tell for sure from the photos.
