bottom rail for Ambassador Elite (?) pool, early 2000's

I’m trying to figure out exactly what this pool is. The previous owners called it an Ambassador. It looks like this: https://www.youtube.com/watch?v=BEFbbqHcE80 , which claims it’s an Ambassador Elite. They seem to be an MA localish reseller(?). They believe it to be about 15 years old and was pretty expensive when they bought it (north of 15k). It’s 24’ round, 48" wall. The bottom track is in really bad shape. I can’t actually find any of the pieces that would show how the uprights and the bottom rail connected. Here are a few pics:

That is a Sea Isle pool by USA Industries. Unfortunately, we do not carry parts for that brand. We recommend trying mwpools.com.

Thanks!

You’re welcome. Good luck!
