My Mantis is a Tulip Wood (might be the only one) and it has the aluminium cantilever. You can see photos on The Vinyl Engine - look in the gallery section and search for my user name (same as here) or in the Blue Angel gallery. You don't need to be logged in to do this.
I love it, best cart I've owned and seems quite at home on my Micro Seiki BL51 with a Stax UA7 arm I bought here on Audiogon.
