Hey Bob, thanks for the response, but I don't think that IS a resorter. The text briefly mentions it, but I'm pretty sure that is just a stock (newer) photo from Lund's lineup. In fact, having looked around, it would seem that they were simply called S-18 in some cases or at least, from what I can tell. Most of the S-18 boats I've found online kind of jive with the time frame the "Big Resorter" boats were made, check this out; https://www.boats.com/listing/forum/images.jsp?entityid=104096991&galleryBack=%2Flisting%2Fboat_details.jsp%3Fentityid%3D104096991
An image search on Google under "Lund S-18" found several boats that looked very similar. I've been promised a photo of the one that I may have an opportunity to buy...but I have one "fixer-upper" already! lol
I'll keep you posted.
Rob
