But - happy news - most of the orchestra parts are VERY readable and still could be used out of the box. In fact, some of the pages never seem to have been used (well not, say within the last 50+ years). The second act was most recently re-copied very meticulously by hand for all of the parts on very good paper.
Even if we can't do the Discovery with full orchestra, I will feel good having preserved Florodora. Too many of these old shows have lost their orchestrations over the years.
