Australian 5 spoke carrier wheels

[Tony Smith]

After much discussion in This thread, it is time to leave David's thread alone and start afresh. It now seems that "D&B" cast on the 5 spoke wheels is the maker's initials for Davies and Baird, a foundry in the Melbourne suburb of Brunswick (in WW2).
Other foundry markings found on Roadwheels and track links include:
Roadwheels
HAD: Hadfield's Foundry, Sydney
NZR: New Zealand Railways, Hutt Workshops, NZ
SEW: State Engineering Works, WA

Track Links
KC: ???
BK: Bradford Kendall
TS: Thompson & Scougall
MALCO: Malleable Castings, Petone, NZ
MP: Mason & Porter's, Auckland, NZ

Any other markings, wether you can ID them or not?
