The size of the prism cutout in the box (shown on your website) would presumably give you the dimensions you need for the prism. I assume the prism itself would fit in the cut-out and the bracket to attach it to the sextant would be on top. I think �747 is a bit over the top. This looks more like the market price for such prisms. http://www.cvilaser.com/Catalog/Pages/Template1.aspx?pcid=1664&filter=0 So, for something closer to �100, you should be able to make yourself a replacement.
