I thought Wojtek was responsible for much of all the BA range but the recent Australians and the odd Paul Hicks one?
Anyhoo, neither the BA BEF, nor the Gorgon Brits look like Mike Owen sculpts to me, although it is possible they may be by the same sculptor despite that.
I don't think any of the old BEF Miniatures sculpts are even in the Warlord BEF range any longer.
