Welcome Jkingo.
Those highly discounted collections are, for the most part, culled from sites such as ours, DCM, Boutje's collection etc. All our work is done for free for the love of the hobby. If it's public domain you'll probably find it on one of the free sites. So please don't encourage the sellers who are knocking off our work.
I agree about the smell - the feel also. And I think that Charlton smelled differently to the others.
