The above listings will surely grow. I will add more values as I find them. A strange feature in the Romanian revenues & cinderellas catalogue is the mention of possible other local chamber of commerce issues:
BALTI
BRASOV
CAHUL
CARACAL
CERNAUTI
CHISINAU
DEVA
GIURGIU
IASI
ORADEA
P-NEAMT
PITESTI
RM VALCEA
TG MURES
TIGHINA

Will add these if found
