Western cylinder collector, Bill Curtiss, did a comparison which may clear up a long time theory that the back of the C.W. Stuarts was the slugged out reverse side of the F & PJ Cassin's Golden Plantation. From what he's found, the back of the Stuarts was the slugged out front of the SHM mold. He also found the the SHM & Stuart bases to match and the Cassin's does not.
Pretty interesting info...
Hope everyone has a Happy Thanksgiving,
