I have a Sangsetia here which I got the hull, plan and plastic set from Metcalf Mouldings way back in the day. I do seem to remember the book -a4, photocopied sheets with maybe a pink / orange card cover. I still have mine from maybe 15 years ago now!!!! But I'm afraid I think it is in my parents loft with my collection of other plans and booklets so I can't help you on that one.
....To be honest though I'm not sure I remember what else it contained separate from the plans apart from useful tips. I seem to remember a bit about making the dinghy, but lets be honest you can find a commercial one which suits (I used an old inherited billings boat one), or not out of the imagination to carve one from wood. I may be wrong on that. It may have said to glue plastic strip to the inside of the hull -then glue the deck on and use milliput to fill the gaps etc. I'm not sure it's nothing which isn't standard construction tips -but I appreciate it's annoying when you don't have it! I think it may have described how to carve the radar dome from wood -but I just got mine from Cap Macquetes I think.
...I may be wrong remembering that lot but considering how few public models there seem to be I can't be too far off?
I haven't sorted an image hosting method I'm satisfied with yet but here's a shot of mine -still a W.I.P!

I never found much but he found allot more pictures of the real thing. Sadly, I'm not a Facebook user so I can't see half of his pictures / efforts. I meant to reply to the post he did but keep forgetting -it may be on here in a search for sangsetia.
...I must get round to finishing my model -it's just a bit big!
