Based solely on the visual appearance in the image posted by Nickos, they do not appear similar, I don't know about a cigar/cigarette burn, I think the marks are too severe and a cigar might not be robust enough to make all three marks.
A poker still seems plausable depending on the shape and they did find one in the gun cupboard next to the silencer, so maybe. 
Of course I'm no burns expert, so what do I know.
Hartley,,,I worked on a childrens' ward where children who were abused by cigarette burns were treated. A cigarette burn is exactly the same as Nevilles' burns,and the only difference is the circumference,which I say is a cigar.
Needless to say,,a hardened nurse like myself cried every time.
