I give my search capabilities a D for the first time around!

That answers most of my questions.
Does anyone have a sense for the quantity of each of the different versions/executions?
Thanks-

: Hello everyone-
: Looking to learn more about the 2447D.

: I am familiar with 2 types of 2447D (that are not gold plated),
: shown at OTD:
:
: http://www.onthedash.com/Guide/_Chronographs/63.Carrera/a.Manual_(1960s)/Carrera_12/c.Reference_2447D_Decimal/

: A few questions
: 1. Were blue decimal tracks always 1st execution only?
: 2. I've seen a 3rd type of 2447D, with a "plain" decimal
: track" 2447D (http://www.imgrum.online/i/BQDSSePgfsI). How
: does it relate to the other 2447Ds shown (I'm assuming these are
: original dials)? Are they after the initial blue dials but
: before the 2nd execution black dials? And if so, why wasn't a
: silver track used for these?
: 3. Were there any black decimal tracks that were 1st execution,
: with silver under the track
: 4. Where there any FISHER dials without the silver track
: 5. In terms of relative production of the 3: blue dials, black 1st
: execution with no silver track, black 2nd execution...does
: anyone have a guess at the mix? I feel like I see more of the
: early blues, but don't have any data.

: Thanks all-
