Ray Gould, collects many of the lodges in old Area 2-G in upstate NY including in some cases their successors. He has recently sent John Pannell and myself a number of scans that are missing from oainages. In some cases, he has suggested some different ways to identify some of the trickier variations.
These are easy, the 120C1a and C1b. The distinguishing characteristic here is the size of the Lodge name:
The 120 C1a has the larger 13×105 mm lodge name.
The 120 C1b has the significantly smaller 8×79 mm lodge name
