Hi Rusty!
The following is the chronological table of CONVER tarot
Mr Depaulis gave me:
*******************************
CONVER, Nicolas : 1760-1803
CONVER, widow of Nicolas : 1807 (according to D'Allmagne.)
CONVER, Mathieu : 1801-1829 (according to D'Allmagne.)
( a gap : namely, an unclear period.)
LEVENCQ brothers : 1850-1858
LEVENCQ de CONVER : 1858-1862
LEVENCQ de CONVER-CAMOIN & Cie : 1862-1871 (Levencq de Conver and Camoin in partnership)
CAMOIN, Jean-Baptiste : 1871-1876 (J.-B. Camoin sole owner)
CAMOIN, J.-B. (= Antoine and Joseph Camoin, J.-B.'s sons) : 1876-1886
CAMOIN & Cie, A. (= Antoine Camoin) : 1886- ?
CAMOIN-MARTIN-GABELLE & Cie : until 1970
************************************
In addition, he says the caption "CONVER" "FRANCE" (on VALET
DE BATON) became statutory from 1808.
So, the BN conver should have been made after 1808:
and, supposedly, by 1829 ...??
