Identifying a Du Pont lighter....any help would be appreciated?

Hello,

I'm hoping there is someone here who would be able to help me identify a Du Pont lighter that my aunt has inherited. I suggested she try the internet as a way of finding out and now here I am trying to find out.

I've tried Google,forums, ebay and am still none the wiser...if anything I'm even more confused!

If anyone can help or has any suggestions of a site that maybe of use would be really appreciated.

I'm hoping that someone might know what model of Du Pont lighter this is and an approximate value.

The pictures aren't that brilliant I'm afraid but on the side of the lighter is a D symbol (if thats any help)

Thanks in advance
