Wish I could help with this but drew a blank. He did kill a snake, in Live and Let Die, using aftershave & a cigar. I wonder if, watching the movie, you might see a name on the can!
"The Book of Bond - or Every Man His Own 007" by Lt-Col William ("Bill") Tanner [Kingsley Amis], a 1965 book referencing to products and culture that 007 used, didn't mention it, so I assume it's not featured in the books. I'd have thought Bond or Ian Fleming would have probably got their aftershaves at the wonderful Trumper's shops in the west end of London though, a haunt of M15 according to John Le Carre, who ought to know.
