In the USA the Horseman lenses are not hard to find. Midwest photo and Igor camera and KEH frequently have the lenses and I believe all 3 will ship to UK.
Since the Horseman FA and the Horseman 6x9 technical cameras share the same front standard and lensboards, this list of lenses that fit on the Horseman FA will also apply to the the 6x9 cameras. So, there are a number of common wide lenses that you can use. http://www.komamura.co.jp/e/lens_list.html
I have every focal length Horseman made for the 6x9 cameras and I will say the Horseman/Topcor 75mm is a real gem. It is one of the sharpest of the group, has coverage to allow for some movements and it will fold-up in the camera. It is not that expensive on the used market because it doesn't look like much, and it is not branded "Super."
