I did find Jamey's postings quite useful, showing many of the same or similar beads. Had not even thought of checking Francis (!), as it is so wide-ranging and short on photos, but it shows a Borneo strand also. Have just ordered the Munan work.

Those green beads you mention (11 together). There are several other beads with the same or very similar base glass, and the same yellow and red trailings, though in various shapes and sizes, including the two largest. Also some with similar translucence but bluer glass. All of them have a lot of bubbles in the glass. These also seem to be the ones Jürgen most suspects of not being Venetian. Altogether it looks as though perhaps 25% of the strand is this "something else" category.
