They're both listed on the col conk website, but is there a difference between the two or are they just the same thing with a different name? 

It does remind me of VDH. Country Uncle lists lanolin as a key ingredient, though, which non of the VDH products have. VDH has shea in it instead. Somebody should take one for the team and find out how similar these soaps are......
Those acutally make me think of the VanderHagen soaps by the names Deluxe, Glycerin, Select.
I think I've read here that VanderHagen and Col. Conk are produced at the same location, but I could be wrong.
