In my habit of disturbing the tomb of long-dead threads, I do usually try to be helpful and constructive. There is an online resource that has photos of the Lindberg Minesweeper.
A longtime favorite it seems, this kit, called a "gem" (with tongue planted firmly in cheek) can be improved with a little work and I believe that is the real value here. The hull lines are accurate enough as are the basic shapes. Some of the armament is shared with that of the Blue Devil (40mm's) and some are not; the 20mm are noticeably better rendered than on the BD although that is not saying much. Overall, I like this kit and how accurate it turns out is a reflection of one's modeling skills. It is not a mere "assembler's kit", this one will test your resolve.
Anyway, Edward Pinniger has had this site up for some time. Not sure if his photos do the 'sweeper justice or rather injustice in this case as it may not show the defects you speak of:
