This is the Amati HMS Prince kit. It has been discontinued for some time. I am currently working on mine. Pretty rare these days. Got mine on Ebay. Paid about $400, but that was a deal. I have seen them for as much as $1000. Very nice kit. The instructions are terrible, however, the drawings are very good. The smaller box is the fittings box, I think the fittings run about $200 now. The drawings and fittings kit are still available.
