Lovely paintjob on those, nice to see them as opposed to the unpainted versions on Artizan's website, definitely getting some for my VBCW.
One teensy quibble though, if those are Metropolitan Police, the buttons should be silvered and not brass. If they are City of London, then brass buttons would be ok, except that the helmet would be wrong for the City force. Also I would query the officer in the cap, the hat band is not 100% for the period, it would normally be plain navy blue. Oh, one last thing are you going to paint them with duty arm cuff bands? Sorry to nitpick.
