Replacing a Gibralta liner

I moved to a new location in Southern Maine and am in the process of restoring a Silkes - Gibralta 16x24 above ground. I have resolved most of the freeze damaged plumbing and will have to replace the liner. There is no paperwork with this pool and I am guessing by the serial numbers on the pump motor that it is around 2000 give or take a few years.
I am trying to figure out what type of coping the liner has as there may be two types; a bead or a lap over. It looks pretty straight forward. I have changed liners in the past but never this manufacturer. BTW this has a bottom drain with a three way selector valve to control and mix the drain with the skimmer. Any advice would be great!!
