hi all,,,is this good or bad?,,only pic i have of this,,does someone have a authentic one of these they could post?..what markings,if any should be on the back?...thanks in advance for any replies,,,Robert

Hard to tell from the photo, but I suspect bad. Need to see the back.

They usually had the maker name on the back, but should never have an RZM mark, as many fakes do.

thanks GPP Guy,,,i will investigate further,,,Robert
