Can someone tell me which is specular or bump?

So I'm trying to change some skin on one of my chars. I like the settings his skin has right now but I wanted a different texture map so I am trying to keep all the node settings for the previous skin and replace the image portions of it with these maps ...

but I can't seem to figure out what's what. Even looking between the current map and this one I still can't tell what's specular/bump. I mean I'd assume almost that S is specular but comparing it to what's already in there that looks more like bump..

can someone please give me a clear answer?

here's a screenshot.

Grey scale maps are value maps with black being 0 and white being 1 and all the shades inbetween being the fractions.  For bump maps light areas are high and dark areas are low.  For specular light areas are strong specular and low areas are weak specular.  Understanding this you should be able to tell the difference from a bump and a specular map.
