I have a question about the hinge brick top plate assemblies. The catalog contains
3937cxx variants, which include the 3937 1x2 hinge brick base and some color
of 3938 1x2 hinge brick top plate. All of these assemblies are counterparts in
set inventories, none are regular.

However there are no assemblies in the catalog including the 6134 2x2 hinge brick
top plate. This is the other piece designed to fit with 3937.

Why? Is there a reason to include one but not the other? Or just that nobody
has requested this? I saw no mention in my forum search for "top plate"

Who knows the reason? Probably nobody.

The whole thing with the assemblies for 3937/3938 was a really wacky idea by
some catalog admin that makes almost no sense. I guess some sellers with used
parts do utilize these listings, so there is some tiny bit of logic in creating
these catalog entries. One lame reason given is that these parts are supposedly
not easy to separate after being assembled. These parts have never come from
the Lego factory assembled, yet the BL catalog contains the long list of assemblies
of various color combinations.

Contrast this with the elimination of part 3830c01.
 
Part No: 3830c01  Name: Hinge Brick 1 x 4 Swivel
* 
3830c01 Hinge Brick 1 x 4 Swivel
Parts: Hinge {Light Gray}
Marked for Deletion

This was a catalog entry that was in heavy use by sellers for years and utilized
thousands of times, yet was eliminated for some wacky nonsense reason. One lame
reason given is the these parts are easy to separate after being assembled.
Another lame reason offered is that the component parts never came from the Lego
factory assembled.

And YET -- we have the opposite catalog position on one type of assembly
versus the second example. So there is no consistency of policy for the catalog.


I consider the whole situation ass-backwards: the most useful listing 3830c01
eliminated but a whole slew of mostly silly listings for 3937/3938.

It's because you can easily destroy this assembly trying to separate it:
 
Part No: 3937c02  Name: Hinge Brick 1 x 2 with Black Top Plate (3937 / 3938)
* 
3937c02 (Inv) Hinge Brick 1 x 2 with Black Top Plate (3937 / 3938)
Parts: Hinge

whereas the assembly with the larger 2 x 2 plate on top is easily separable.

I respectfully disagree. The larger plates also easily damage the assembly. I
believe the reason it is not in the catalog is due to the nature of how the hinge
can be built with the large top plate. We would need two entries for every one.
One with the plate facing forwards and one with the plate facing backwards. Both
of these techniques are used in official sets.
