Hi,

Item 238 looks a bit like an electroscope, but from the photo, there is
a lot that can not be seen. The foremost question is," is there a gold
leaf attached to the central hanging thing (or should there be)? What
is electrical isolated from what and how well? Do the side things slide
and are the hollow, with lenses? If the answers are yes to these
questions, this could be an electroscope used to measure ionizing
radiation. I have seen electroscopes mostly like this but with only one
side assembly.

Thanks

I sent some questions about this device to the owner but haven't heard
back yet, I'll let everyone know when I get a reply.

Another tough set this week, I still don't know for sure what three of
them are. The answer page can be seen he
