New Tribe Harnesses

Hi. I’m new to this site. I recently acquired a bunch of almost new New Tribe harnesses at an auction sale, that I am looking to sell. I think the green one is a standard model and the red is a Twist Kids. Can anyone confirm this and maybe give me an idea of what they are worth? The green one was made in 2008. No date on the red. I have a bunch of both. Good for a summer camp maybe? Thanks.
