Have tried to contact billing boats to see if they have it? they’ve started to post instructions for some of their boats. If they don’t have it, then you may want to consider the Norkap by them. The two look rather similar to each other and if you really want it to look like the progress, you could always kit bash. By a strange coincidence I’m in the process of building the Nordkap and found a site that has photos of their boxes, but not much else.
