Old pool light

I have an old pool light that completely failed and need to be replace. The problem is that the attactment screw is not at the 12 o’clock position, its at the 2 o’clock position and I can’t find any light that is configured like this light. The bottom has the typical attactment, like most of the light have. The light is a little less than 5 inch from the lens to the back. I hope some one has an idea, because I would really like a light in the pool

Thanks
