Default Reading old capacitor values

In the back of Vol. 2 of the RSGB Radio Communication Handbook it shows

two
types of ceramic caps. The first has axial leads and the first color band
is wider and is TC then 1st, 2nd, M, T. The other has radial leads and

has
a dot for the tip then 1st, 2nd, M, T.

I have seen some old small block caps just marcked with pF values.

British 1940s components that are driving me dotty
Small rod types with body/end/dot colours
red/red/green
orange/orange/green
yellow/purple/yellow
brown/black/brown

what meaning to the yellow and green multiplier dots ?

and Hunts make, brown cased small block, flat leads, with code oc/3100
impressed into the encapsulation
none of them measuring anything like I think the colours/codes mean
