Pottery in horse-drawn Russian carriage (6)

I believe the answer is:

This clue is a triple definition!

'pottery' is the first definition.
(pottery made by the Troika group)

'in' acts as a link.

'horse-drawn' is the second definition.
(I've seen this before)

'russian carriage' is the third definition.
(I've seen this before)

(Other definitions for troika that I've seen before include "Russian three-horse coach", "Russian vehicle pulled by three horses", "Russian horse-drawn vehicle", "Threesome", "Russian carriage pulled by three horses abreast".)

I've seen this clue in The Telegraph.
