How many types of these vertical hangers with zinc clips are there? All of them appear old and have wear they have different RZM codes 1/35 1/38 the clip is what makes everyone reluctant to purchase. I am confused. It is stated that "I have never seen a real one with a cast or pot metal clip?" then what would make it original with a pot metal clip??? If the rest of the construction is "textbook" and it has "age" and is not new is the clip that which defines it as a repro???? these do not resemble modern repros at all and side by side they are identical to "known accepted period vertical hangers" so these are not "textbook" due to the clip??? if a faker went through the trouble and cost of making such a near perfect and aged copy why did they not use metal plated clips???? These were around by the hundreds back then and basically worthless. I have five myself three unmarked and some RZM stamped doesnt make any sense looks like a classic case of textbook and accepted weird
