On a LC 20ga 5E I used to own the Cody letter had almost nothing.
Cody gives the bare minimum of data from their records. LCSCA goes farther, which is nice, but in no way can Cody really claim superiority of data as they are looking at the same record.
Arguing one as official versus the other is of little value.
Records on many of our guns are scant. Some gunmaker ledgers have very little data beyond serial numbers, dates, and original buyer, like the record on my Alex Martins. Others like Purdey have much more, to an email, they sent me a scan of the original Ledger entry, interpreted the script, and answered follow up questions. The details Purdey recorded was awesome for determining original features; All for no fee. Pity LC recorded so little.
