Pachypodium but not saundersii

[teo]

I found this plant a few years ago in a garden centre (on the cactus shelf of course) and I labelled it Pachypodium saundersii but now I don't think that is correct (the spines/thorns are wrong). I think it is another Pachypodium, maybe horombense or rosulatum?

Indeed, not Saundersii, leafs are too flat on this one.

Can't positively ID it though. Is it a single plant? How old? Could it be etiolated?
Maybe (maybe!) Densiflorum...

It's a single plant, maybe 3-4 years old. It has been inside behind a south-facing (triple-glass) window but it might be a bit etiolated. Densiflorum seems like a possibility.

If the soil is hiding a caudex, the branching could be just like a densiflorum. Although in that case I would expect the trunk to be thickening at the bottom. Your specimen clearly isn't. Tough one. The spikes are pretty similar to densiflorum as well. What confuses me is the fury coating on the new growth. I have never seen that before.
