By the way, overlaying one over another depends on the image dimension of the images(s) is being imported in arc map.If images with same dimensions are imported then these images overlay one over another.In this case arc map creates two files (.xml and .ovr)for each image. You need to just drag and ...

You could assign a projection to your map in the platform you are working in. For example, you could first try to assign a UTM Zone 11 North projection and overlay the map with a base map (e.g. Google Layer) and see whether the features of your map align with the features of the base layer. If not, assign UTM Zone 12, and so on.

Another - more interactive - option is the Vector Bender plugin. It does to vectors what georefencers does to raster. This feature is also known as "rubber sheeting". There is even a video showcasing how it works: https://vimeo.com/96142479
