Very, Very BAD fake !!!!!!!!!! This style of 1870 can be found on ebay in several different configurations. Usually as a pin back marked Deschler and son. However it can be found with different makers marks. This particular cross jumps out as fake right away because it is a screwback. As far as I know there are NO 1870 Ek1 screwback crosses. Next --If you look at the screwback itself, it is RZM stamped. There are no screwbacks (even in 1939) marked "RZM" Even in pin back form these fakes are easy to spot by the style of the numbers in the 1870 date.
