We need more of your serial number to determine if SG or S'G'.
Split serial number block: Started out as Irwin Pedersen after IP got the boot the rest of this block became S'G'..... 3,212,520-3,250,019
Next block started out as SG 3,250,020, then became S'G' before the end of this block ~3,651,519.
It's complicated... Just give us more of your serial number...... and home address ! just kidding, Don't trust Bruce the Swami.... Never mind he's probably found you by now
