Alan, I think your job will be manageable if people send you pictures of weights that have labels or are documented in an acceptable publication. It would be best if people sending pictures would do the background work on attribution. That will spread the work around so one person (Alan) won't spend so many hours checking attributions.
One thing that is difficult about Murano weights is trying to figure out exactly when they were made. Few sources have the years. It seems to me that c.1960 seems to be the biggest time for Murano weights, but it is hard to know for sure.
