Thanks very much for the advice! Basically you both said the same thing
I was reading another column which talked about more aggressive cleaning and I thought it was wrong so very glad I asked.
I'll try to get better pics soon. I haven't been able to find a signature or foundry mark, all I know is it was listed as a Mene when my Aunt aquired it in the 70s. The base is marble. The dimensions are about 5 inches across the base and 4 inches tall. I believe it is bronze from the look and the listing but I'm not sure. I can't seem to find it on any Mene sites I saw so thank you for the link!
The nest has a lid which lifts up I believe to house an inkwell, but the piece is hollow inside clear to the marble.
I never realized it might be valuable till a friend mentioned it was so I thought I should find out more about the piece.
Thanks for the quick replies!
