The only ST Montes I know of are
Number 077 Mallard Green which is in Malta
Number 080 Jewel Violet never seen a pic thou
185 Jewel Violet which is concours mint IIRC
190 Mallard Green which is LHD and also not a Monte but a even rarier Martini
So theres two others which might be LHD and maybe not even Jewel Violet.. and the number of ST Montes is rumoured at 6 so there maybe not be anymore at all
