Lanny, in my opinion the correct range is on 240-243.

In these last months I saw some Orange Boy on 243xxx range with 11630 hands type!
We have to ask to Museum for a pic of his last Orange Boy.
And I saw a 1163P with 11630 hands with 245xxx serial too.

So, always in my opinion, we can find orange strype hands till 242xxx, after that we can find 11630 style hands.

In my last interview with Jack Heuer I discover some interesting things about these dials!

: Hello Gents - is there a defined range of serial numbers for the
: "orange boy" or "gulf" dial variation of
: Autavia's?

: Any help - appreciated.

: Best,
