[Adjuster]

Thanks for the suggestions. I had hoped not to resort to a hammer, but no doubt that's what I will do if all else fails. Acetone sounds worth a go first though, perhaps in sealed up in something like a small jar to allow it to penetrate for a while.

The main target for these might be another old set in much worse condition to be attacked later on, rather than experimenting on this present one. Maybe it's a bit daft, but somehow I wanted to salvage something from the Phantom Fiddler's efforts.
