Hi, that does look like one the torso's that Sarah Cowan used to make at the Enterprise trading Estate incarnation of Okra, my knowledge of Okra comes from being an ex employee of the Studio in the 1980's, 90's and I did a bit for Dean and Karry before the Queen Street studio was closed (a difficult time for me as I had a health problem).
The Enterprise era of Okra was quite a turbulent period with a lot of ego's and the guys constantly needed a lot of guidance/instruction from Richard.
