I love this hobby. I'm authoring part for almost 15 years and still come across things I have no clues about. Given that I read:

http://www.ldraw.org/library/tracker/ref/numberfaq/

I have no idea how to number the top and bottom part of the Animal clam I just fixed:

http://www.ldraw.org/cgi-bin/ptdetail.cgi?s=30218

and how to number the assemblies of the closed and opened version.
(Is it further worth modeling its alias https://rebrickable.com/parts/30218/clam...inner-lip/ or just go with a renumber).

Some goes for double injection:

how do we number them? Any links in the FAQ?

IMO it should be made regular subparts

Today I would give them a suffix -f1; 'partnumber'-f1 , 'partnumber'-f2. It's the same part, but in two different states.

I think the p-suffix is the best here, if not the correct lego design ID is known.

Examples:
Rock 4x4x1.333 and Rock 4x4x1.667
Plate 1x2 with rubber tip, 61406p01 ....
BURP 6083p01, 6082p01

Looks like Steffen has a different opinion:

http://www.ldraw.org/cgi-bin/ptdetail.cg...152p01.dat

but to me this is not an assembly but a multi injection part:

I agree.
Definitely P01 for me.
See below...
I could not see the pictures initially, but found them on the PT.

Although I could not imagine first, the way it looks to me it is a double injection part.

I found now both pieces and I think it is the following way:

The older 30152: Assembly
The newer 10830: Dual Injection.

As the Trans-Red is only available as the 30152 variant, I would go for a ...c01/...c02


10830 is visibly different from the  30152 and shall be a different part, i.e. no alias, as the frame is 'much' thicker.

edit: What makes me wonder when looking at Willy's pictures, is the lack of the little dent on top of the frame that 10830 has, but seems to be owed to the perspective.

edit: revised below

Brickset "Element count" field makes it clear:
30152 and 90463 are assemblies (Element count=2) -> c01

10830 is Dual Injection (Element count=1) -> p01
According to images, 30152 and 90463 have thin edges, but 90463 has a thicker glass, while 10380 has thick edge/thin glass

If the Element count would count determining if it is an assembly or a multi injection how would you rate these:

https://brickset.com/parts/design-52210 (Element count=2)
https://brickset.com/parts/design-2634 (Element count=1)
https://brickset.com/parts/design-47847 (Element count=5)

I tried to remove the lens of the 30152 - no chance. It is further more inserted seamlessly.

OK... Element count is not a clear criteria...

Glued?

No glue on the borders of the lens but the gap you see on the picture is closed with a transparent finishing on the surface. Scratching with your nail over the outside ring you cannot feel any imperfection - perfect surface as if the spine of the lens had melted into the black ring.
