Hello Sorry for not answering have been away. I found the inclinometer from searching the internet for chinese manufacturer http://www.gemred.com/en/product.asp
i see they have updated the product list with what looks suspiciously like the Wixley model.
as i am always over there on business i got a friend to get a "Sample" for me cost US$40. Here in Australia the only one i could find was built into a laser level and was pretty expensive.
