Identifying a brass drinking vessel

I have a brass drinking vessel very like the one pictured on this site. It was identified by the collector as a marriage cup. The one pictured on your site is identified as a wine cup. On my cup, the lip one side is somewhat wider. Underneath that lip there is oriental script. There is a handle on the cup large enough to fit only one finger on one side only. If one were right handed, and holding the cup, the smaller lip would be facing. It seems to me if it were a marriage cup, there would be handles on both sides. As in your photo, mine has the three legs and two post-like attachments on each side on top. Then the one I have has a geometric type design around the cup area - three rows of squares within squares. My question - is this particular shape vessel then identified with wine only? Or could it also be a marriage cup? It appears to be quite old. If I send a photo, would you be willing to help identify it? I can't seem to find any dealer in antiques that can identify it's aprox age or value.
