Geno, no I not have the details about it. Strank not mention the Mod so I think it is a special order. He not mention the S.N. so we dont know it it is a true pair or a composed pair. In my opinion it is a true pair, because I think it is a special order and made under Verrees name.I think a full condition rapport can clear all your questions but Stank not answers mails in english but you can try.
