What coral is this?

Yeah maybe, it's a branching something but looks like it could be a Duncan with the greenish wrap on the skeleton. Hard to say until it opens. I've never seen either with that long of straight branches before.
 
Cloak, after looking at your link could be a frogspawn too, doesn't seem to have any tentacle extension so hard to say but could be the torch.

torch will have longer tentiles frogspawn looks more like a hammer just different tips. imo not a Duncan, Duncan dont have a long base like that

You're probably right on the length of the Duncan bases not being that long. I know what torch's and hammer's as well as frogspawn look like. The branching hammer that I have has much shorter bases and they are attached together at the bottom, not single like the picture
