Magazines with and without date stamps or other identifying features

[DHCO]

So with the impending passage of 1224 I think a discussion of which magazines have date stamps and which ones don't would be good for researching the effects of this law. Could we compile a list of magazines for various models of guns that are confirmed to not have date stamps? Or is there a list already available somewhere? Would it be better to list magazines that do have date stamps rather than ones that dont? This would inform the community which magazines we should stay away from to make enforcement of this law easier..
