Well the ones in the CE's were cheap plastic (like the one on the left of the pic you posted.... that is the old CE version I believe) but the ones i linked came much later (not to long ago). I do not know what the recent ones are made from but I would say there recent ones look to be similar as you said even if not the same material.
Anyone here who got the ones from the Beth Store have any info on the material they are made from?
If the pic on the bottom is the one you are talking about it does look slightly different for sure. Pretty neat if it is a different material, I can tell it looks like resin. No telling how much that would fetch if it is a rare dev only version. A LOT
