You might try asking on Haley's Tsang Sather's Facebook silver glass group -Lampwork 104 Silver Glass - because I know she is owner of many of the batches, old and new... (or message her?)
I know that generally speaking if they are transparent rods, they are reducing, opaque they are striking, but there are also some that do both (like Clio for instance) but some of mine that are the same color but different batches look different.
There was a challenge on the Terranova versions recently, and I may be mistaken but I don't think that is being made anymore, so if someone loves it they might want it (or at least 1/2 lb or lb of it).
This is Hayley's group:
