That was reported be an eBay seller and not substantiated, though likely true (why would they lie?) so probably worth counting, so then: VER$ S/N Range ===== ============= 1AAAA: 2401Axxxxx 1 sample 1BBBB: 2401Axxxxx to 2601Axxxxx (metal back) 1BBBB: 2623Axxxxx to 2713Axxxxx (plastic back, need source for 2623A) 2CCCC: 2718Axxxxx to 2745Axxxxx 2CDCC: 2750Axxxxx + As for left-hand and right-hand zippers - that's silly, who could care about that? (making a note to check mine...) Thanks Dave --Bob Prosperi |
