I've managed to find my copy of the SU Reference Catalogue in storage and have posted here some of the pages I think are relevant to this discussion. Would have been nice to have this earlier but better late than never.
You'll see many of the parts and part numbers in the NSW Police SU AUD488 specification sheet I posted earlier line up with the following.

First we have clarification of the meaning of the terms LEFT and RIGHT. For a transverse engine Mini they are taken from a view in the drivers seat. The throttle and choke positions use the same method.

This shows the SU part number for the needles. Initially a CP4 (AUD1118) was specified for the AUD488 spec carbies, replaced a little later by the BG needle (AUD1067).

The needles were the fixed type to suit 0.090" diameter jets. The spring was blue (AUC4587).
The 0.090 jets can be identified by the lack of a marking groove.

As mentioned in earlier posts, the jets to suit the required 30 degree float bowl angle are AUD9098, identified by a black head colour and white sleeve, and AUD9102, also with a black head colour but black sleeve.

The float chamber adapters to suit the 30 degree incline are AUC1336 coloured mauve, and I assume its mate AUC1316 being orange.

The 30 degree float chamber is AUC1310.
