Thank you for sharing this update, I'll edit my post concerning the 96HU. Between the beginning of my work on this article and the end I went from unique to 2, 3, etc... for some references.
I don't know if the 5131G is yours (if it is congratulations) but it is for sure a goregous piece. The white metal helps focusing on the enamel work.
Thanks again for you input and nice comment!
Cheers, Mark
