Old pool liner replacement

Have an old pool that I need help identifying the type of structure. The details in the plans found in our homes file at the local building dept says Glamour Pools by Aztec. I am in NY anyone have an idea how the pool is constructed? We need to determine if it's worth saving or replacing. I think it's from the 80's we used it last year after moving in and the pool had not been used in 9 years. It's works ok small leak near skimmer that's about it. Any help would be appreciated
