Four Shaw

[STSH]

Along the same lines as another message I posted, there are four separate pages of Shaw Brothers listings.
IDs 1816, 1388, 893 and 506.

506 is the mother lode, listing about 700 films.
1388 lists films from the '80s and '90s.
The other two only have a few each.

Can any or all of these be merged ?
Are there any differences which matter ?
If so, it should be a simple matter which can be done by admin.
