Early-WWII Transitional Airfields

Do we have, or can we compile, a list of the early-WWII "transitional" airfields, spanning the gap between the last Scheme M airfields and the fully dispersed temporary WWII airfields?

I have a few noted, and they seem to fall into two categories; those that are pretty much a temporary version of the symmetrical concentrated expansion era layout with the living areas immediately adjacent to the technical site (I'll call these Class 1 for now), and those where the admin and accommodation areas start to be more and more dispersed (Class 2 for now).

"Class 1" sites include Holme-on-Spalding-Moor, Pocklington and Polebrook.
"Class 2" sites include Molesworth (SHQ and some living accommodation adjacent to the technical site, but the communal areas are dispersed), Chipping Warden (Symmetrical concentrated tech site with SHQ, dispersed accommodation sites) and Goxhill ("grid-iron" concentrated tech site with SHQ, dispersed accommodation sites).

Often with at least one J-type hangar, most of these sites tend to have temporary versions of expansion era buildings too; large MT yards, TB guardroom at the main entrance before or facing the SHQ, TB scaled-down main workshops and stores, fuel dumps close to the tech site, etc.

Some of the west-coast airfields in Scotland could well be included, i.e. Wigtown and Ayr (Class 2).

Just thinking out aloud, would Llandow (ASU) be considered as a Class 2?
It has expansion era building designs, J/K hangars and SHQ in the tech site but also temporary buildings and dispersed communal sites.

To use some local sites as class examples, albeit all bomber stations with one J-type and two T-2 hangars (and introducing a new class for sites which have the requisite structures, but are well on the way to being a non-symmetrical fully dispersed airfield):

Class 1: Polebrook
Class 2: Molesworth
Class 3: Chelveston

Let's see if we can come up with a basic set of ground rules for these.

All sites will at the bare minimum have been constructed during 1940-early 41, and not be late (L/M) Expansion Scheme sites.
i.e St Eval and Wick don't count as, while they had temporary timber support buildings, they had C Type hangars.
Similarly sites such as N. Luffenham and Oakington with J Type hangars don't count either, as they had permanent support buildings.

The main obvious feature will be one J Type hangar with two or four Type A T-2 hangars close by.
Other regular structures will generally be a 518/40 watch office, 15556/40 ops block, large MT yard, 1940 design bomb dump, etc., as would be expected from sites where construction began in 1940.

Note that all so far identified seem to have been bomber stations, with the exception of Ayr which (if it had a J Type) appears to follow the "Class 3" layout but being a fighter station didn't have the same ops block or bomb dump.

EDIT: I've added "Class 2b" for those special sites that have the symmetrical layout but don't have the minimum J Type + 2 x T-2 hangar arrangement.
