I think what is important is that the rifle is tied directly to the case maker Winship indicating a possible factory set vs. a pieced together set by someone after the fact.
The JTC letter does not mention a .410 barrel or a cased set, but it sounds like the recording system for ledgers didn't clearly specify these things.
The JTC letters I have and have seen typically state the warehouse and ship dates and possibly the recipient of the rifle. But, doesn't say specifically "sold to" recipient.
This JTC letter says "resold". The actual ledger page is absent so this cannot be verified. Maybe JTC used the word resold vs. reshipped??
All the potential reasons why may be interesting, but are purely speculation.
The bottom line is this cased set appears to be legit with some documentation whereas few others are documented as cased sets.
