how do we classify a weapon tourist,origin,time period ?

[A. G. Maisey]

Actually Jens, there is a very well established system of classification that is used with keris, but it is virtually useless unless one is able to adopt a Javanese frame of reference.

I do agree, that in discussion of weapons, or for that matter, any physical object, good photographs and relevant data are second only to the presence of the item under discussion.
