Makes me wonder what I bought then; new, stamped PSD and mk2 spec. Is this one of a questionable batch that was on the go a few years ago, alledgedly PSD but marketed by a guy called Juan iirc. Either way it's a case of buyer beware I suppose and apart from the keyway problem, they have worked just fine. Also apologies to Insight G40 for cutting across his sale thread. Don't doubt they'll sell mate.
