Richard, A full description of ACI 1160 might add clarity. (this post is not it either)
It states that SCC refers to the colour, and not the type of paint used.

Gina, I have the ACIs for 1940, 41, and 42.

The appendix talks about: (under the title of)
Basic paint:
For Bodies. Wood and metal
Cat No. HA 5715 paint p.f.u. Brown S.C.C.No.2 special spraying C.S.1733)
Or.
Cat No.HA 5638 (or HA 5147) paint p.f.u. Spray Khaki Green No.3 (C.S. 1429) until present stocks exhausted.
Then,
For canvas covers and hoods
Cat. No.HA 6194 Paint Bituminous Emulsion S.C.C. No.2 (T.S.143)
And then,
Cat. No.HA 6145 Paint Bituminous Emulsion Khaki Green No.3 (C.S. 1442)
until present stocks are exhausted.
The first half of the above relates to "A" "B" and RASC Vehicles, the second half to artillery and search light equipment.
Then for steel Helmets:
Cat. No. HA 5861 Paint dark brown textured matt finish (C.S. 1736)
Then for tentage:
Paint Bituminous Emulsion Cat. No. HA 6193 S.C.C. No.1,
Or:
HA 6179-S.C.C. No7
And lastly for Bridging equipment is states:
Special waterproof and anti gas paints will be used as directed in the hand book on maintenance of these equipments in S.C.C. No. 2.

Then there is a column Of "Dark Patterning" for the "A", "B", RASC, Arty, and searchlight equip, with three options.

Then Under the notes column, (for the above vehs. and equip) it states:
Cat. No.HA 6184 Paint Bituminous Emulsion S.C.C. No. 14 (T.S.143) may be used if the preferred options are unobtainable.
There is lots here that means little to me. Given time I can photograph and post if required.
There is a general note that in future S.C.C. No. 2 will be considered the general purpose paint. Existing stocks of K.G. No. 3 will be exhausted.
S.C.C. No. 1A will be the paint of dark patterning and existing stocks of Dark Tarmac No. 4 will be exhausted..

Does anyone one have an index for the Army Council Instructions (A.C.Is)?
