Signs of lead rot?

[Zaheer]

Apologies if this is in the wrong subforum, signs of lead rot on the figure on the far right?

Looks like it, yes.
Try gently burnishing the crystaline areas with a blunt needle, if it returns to shiny metal you may be able to recover it with a bath in a strong brine solution (the salt neutralises the rot causing acids) and painting/varnishing.
If the metal stays dark or worse flakes/crumbles the model is a goner.
