Sigma 28-80mmD lens (Is this for Pentax?)

Can anyone help here and tell me if this Sigma lens is a Pentax lens mount. It is for sale on Ebay. Here is the link with photos. Sigma Zoom 28 80mm 1 3 5 5 6 Macro Lens | eBay

I'm betting it's not for a Pentax because a) the bayonet lugs look too long and b). the electrical contacts are in the wrong spot and are the wrong type.

BTW: Welcome to the forum!

Looks like Nikon to me, you can see it has 2 sets of numbers around the aperture ring.

Nikon for sure.

You can see the lug sticking down past the flange for the lens mount

It is definitely Nikon mount, but the 2 sets of aperture numbers are also present on some K-mount lenses. The lower set provides compatibility for those cameras (ME Super, KX, LX, etc.) having an optical window for to view the aperture within the viewfinder.
