That's a nice one! It might take some clever iterations of the search function here but I think you'll find some other examples.
I'm aware of (i.e. in possession of) the 15yo undated version with the label that looks like VWFRR (minus the second "R") and the dripping red wax and I know others have dated versions similar to this.
Regarding the dripping red wax, by definition all VW products came out long after MM started their thing, but a combination of export-only, company size, and family/brand history kept away an injunction as I understand it. (Cuervo had none of the above to fall back on.)
Tasting notes: best S-W I've ever had. Rich, cherry-burnt-butter nose and brandy-like finish.
