This golden specimen is one on the best I have seen from this place.
Congratulations |
Thank you Philippe. I don't have nearly enough space to have everything on display, so many specimens reside in flats. I hadn't seen this piece in quite a long while and it even surprised me when I opened the box :>)
Hope you are well.
Michael
