Replacement bottom rails

Hello-

We have just acquired a used above ground pool- 15 x 30oval, but do not know the brand. The only part numbers are on the plastic caps (2495, 2496, 3495), and no pools I’ve found online seem to match. I’m looking to replace about 6 of the metal bottom rails, but I cannot seem to find any that match the exact dimensions of ours. I will attach a photo, but the dimensions are 3/4" wide, 3/4" high, 56-5/8" along the long curve, and 55-1/4" straight across from end to end. I’m looking for anything that would work, whether or not it is an exact match in every way- we just want to get this thing up! Thanks
