The helmet shapes are odd in that Foundry pack too - more like Chico Marx's hat than anything any British Police Force ever wore.
I don't think anyone has mentioned yet the Victorian police officer (in cape, blowing whistle) in Black Tree's Doctor Who range (under the 4th Doctor category). Not bad, but there's only one of him.
I hate to say it, but my favourite late Victorian policemen are probably the ones Kevin Dallimore converted from Foundry Zulu War artillerymen for a South London Warlords convention game. I don't know if the base figures are still available - Foundry also used to make artillerymen in the "airpipe" helmet which some Police Forces used to wear.
