I tried something that I never sen done before made my own Transformer. The original G1 line of toys never released an Arcee so I took up call and made one. Arcee started out as a Mystique figure but soon got a complete overhaul. The chest, back and ankles section are all made of galvanized steel and were then sodered together. The helmet is actually the helmet of a McFarlane Toys Kendrell Bell figure but has been grinded down to give the appropriate look. She goes right along with the old TFs as pictured. And as a small side note this was my first custom.
You may have stumbled into something big here since there are tons of Transformers collectors out there! If you make the right figure you could probably sell it for a nice chunk of change.
She looks good, for a robot
