If you have access to FTP, look on ftp.apple.com, in /dts/aii/ftn.  The
file "ftn-about-92-06" lists all the type and aux type assignments known to
the system software (as of June, 1992).

Here's the relevant portion of the list:

File Aux.  3Ltr File Type Description
Type Type  Abv  (File Type Owner)         Auxiliary Type Description    Date
----------------------------------------------------------------------------
$E0       LBR   Archival library          Application Specific
$E0 $0000       ALU library               Carolina System Software
$E0 $0001       AppleSingle File          Application Specific          11/90
$E0 $0002       AppleDouble Header File   Application Specific          11/90
$E0 $0003       AppleDouble Data File     Application Specific          11/90
$E0 $0005       DiskCopy disk image       Application-Specific       ***05/92

$E0 $8002       ShrinkIt (NuFX) document  Application Specific          07/90
$E0 $8004       Davex archived volume     Application Specific          05/90
$E0 $8006       EZ Backup Saveset doc.    Application Specific          09/90
$E0 $8007       ELS DOS 3.3 volume        Application Specific

$E0 $800A       Replicator document       Application-Specific       ***05/92

Shrinkit archives (whether .SHK, .SDK, or whatever) are usually $E0/$8002.
However, the Shrinkit program doesn't actually require this...you can
unshrink an archive no matter what its type and aux type are.

The exception to this is a .SEA file.  Since these have to be executable on
the IIGS, the correct file type is $B3.

Note that .BXY isn't, strictly speaking, a Shrinkit archive--it's a Binary
II file with a Shrinkit archive inside, and its proper type and aux type
are $E0/$8000, the same as other Binary II files.
