I would say that the one that comes closest is this one. But we should also observe all the details. Attached are the sizes (diameter and height) of "ordinary" Regency kings.
I'm trying to go back in time, but unfortunately, in 1944, the entire village of Dortan, the world capital of chess manufacturing at that time, was reduced to ashes, all the machines were looted and I will keep myself to give other, more traumatic details.
At the end of this video, you will see Joanny Lardy (on the left) with HIS Regency set.
Please read this text too . You will understand better why it is very difficult, apart from certain particular sets, to attribute these old sets to one house rather than another.
So... would I have any luck with any of these knights/sets? I'll delete the non Chavet or whole post if inconclusive.
