these are two (I'm assuming Mexican) 162.7s with rdp but the mold line stops at the wire groove, not {MLOD} as the book suggests for no emb Mexico. also notice one has a sharper upper wire groove and the other is more rounded. also the left one has a prominent ring around it on the top of the dome, obviously a mold feature. one is a tealy green and the other a teal aqua-and they are both available if someone is interested-any info would be much appreciated. thank-you.
