We have a Brass Chain Door Guard nos by Brainerd Mfg.  The brass receiver measures about 3 1/2" x 1 1/2" with the slide chain measuring about just over 5" in L including the ends.  It reads Solid Brass on the top but on the side it states "Hardened and welded brass plated chain.....".  The package shows quite a bit of wear - it is sealed.
