Escada Homme 
Escada (1993)
DISCONTINUED

It's interesting to find links between perfumes, and this one does smell a bit like Héritage.
But to say it's a copy is contentious, and hard to prove.
Not only because there's no copyright on perfume, but, since the My Sweet Lord trial, it's difficult to prove that any copy was deliberate.
It could always be a case of subconscious plagiarism, as the judge said about the close similarity between the George Harrison hit and He's So Fine by the Chiffons. It's as though Harrison had the tune in his head, but didn't realise he'd heard it before - and didn't remember.

So maybe the reason why Escada Homme (1993) smells like a version of Héritage (1992) is because the (un-named) perfumer had smelled it somewhere before and 'didn't remember' when they were composing their own aromatic Amber for men.
Not only is it lighter than the Stentorian blast of Héritage, it's also lower quality with a screechy dog whistle overtone. There's also a fruity note which starts as orange in the head and becomes more like pineapple as it sinks to the body.

Escada Homme is less consistent when it comes to volume; it rings out from the paper for the first few minutes, but after a couple of hours (on a shirt), even a whole millilitre fades to a low hum. Unfortunately, the dog whistle doesn't go away.

So, in my opinion, it's not worth chasing after this. Better choices would be Safari for Men (also 1992), the Guerlain, or maybe some other pineapple thing you may have heard about...
