The original version of the instructions (either 4281689 [IN] or 4281693 [NA])
show four 32140 in what appears to be the old pearl dark gray (PDG) color.
These parts also have a *long* history in the inventory change logs for the set.
(1) The original inventory on June 19, 2005, had four PDG 32140. (Score - PDG:
4; DBG: 0)
(2) On June 17, 2006, the inventory was updated to add two DBG 32140 without
removing the four PDG 32140. (Score - PDG: 4; DBG: 2)
(3) On May 29, 2008, the four PDG 32140 were finally removed leaving just two
DBG 32140. (Score - PDG: 0, DBG: 2)
(4) On September 22, 2008, an additional four DBG 32140 were added as a separate
line item. (Score - PDG: 0, DBG: 2+4)
(5) On September 24, 2008, the line item containing the two DBG 32140 were removed.
(Score - PDG: 0, DBG: 4)
(6) On August 9, 2014, the original four PDG 32140 were added back in as alternates
to the four DBG 32140. (Score - PDG: 4 as alternate; DBG: 4 as regular)
So according to the change log, it looks like DBG 32140 were used as alternates
to the original PDG 32140 in some sets. But where does this leave the fact that
the later version of the instructions shows four DBG 32526? Why haven't these
been noticed before now and added to the inventory in some way? Did all of these
members just not realize that the 32140's were really 32526's?
Since the original inventory here on BrickLink had four PDG 32140 and the instructions
seem to also show four PDG 32140, those are the ones that should be in the Regular
Items section as they originally were. I will get those moved.
So now we just need to prove the DBG 32140 and/or DBG 32526.
After looking at ~100 used set listings from past auctions, some sets had PDG
32140, some had DBG 32140, and some had a mixture of both. I couldn't find
a sealed one that showed the DBG 32140, but with that many showing up in used
listings and the inventory change request history here on BrickLink, I am 95%
certain that some sets came with DBG 32140.
The only thing I can't find is any existence of DBG 32526 in the set besides
the set of instructions. Until a time that it can ever be proven that those parts
were ever included in a copy of the set, the inventory on BrickLink remains as
correct as possible concerning these parts.
