Thank you for that information dick.
https://www.world-war.co.uk/Cairo/colombo.phpLooking at this link for Colombo, I think I can see:
First photo, labelled "1926" - white hull and upperworks, primrose yellow funnels (and spotting top??)
Second photo, labelled "probably in the 20s" - white hull and grey upperworks, black starfish, white spotting top
Am I seeing right? These bright colours would make a good model given we have the 1/350 Calcutta kit now.
Colombo served both China Station and East Indies so certainly could have worn both. In the second photo - is the rear superstructure (under X turret) white? Or is this a sunlight effect? I have seen similar on photos of HMS Durban.
