Before treatment the miniature seems badly damaged, but after removal of the oxidation layer the condition isn’t so bad.
There are very thin crackles on some details, mostly on the fur and chainmal, so these will be disappear easily after priming.
The face and the helmet horns will require a small intervention: the face a bit of smoothing near the nose and the horns loose a bit of shape and pointy ends – some green stuff will repair them.
The biggest damage is on the base, I will first straighten it, eventually with some small pliers and rubber/plastic covers (to not damage the metal), then I will level the bottom or make it thicker with epoxy, eventually mounting the mini to a large base (plastic, resin or high density plaster).
This time a multi-part miniature, lead rot or some other trauma detached the small creature from the carpet:
Before treatment the figures were really ugly and looked damaged.
After it, the carpet can be used with minimum further intervention, just a bit of cyanoacrilate or liquid putty in a pair of small details, to better define the damaged pattern. The hole will be hidden by the wizard figure placed on top of it. Of course it’s also possible to seal it and recreate the small part of pattern there, in case it will be used “standalone” (not a lot of sense in it, though).
The wizard can be painted right away (well, after cleaning the mold lines that are still there 😉 ), the small fissures in the mustache will be used as further details.
The small familiar/homunculus has to be of course reattached to the carpet, where I think it originally was waving. The damage on him is also minor, cyanoacrilate or liquid putty will seal the small fissures.
