But outside of a few slips that I suppose must occur, there shouldn't be any duplication of serial numbers.
#JOSEPH DELANEY TORRENT EBOOK NL SERIAL NUMBERS#
Serial numbers are a rough guide as to date of manufacture. Ford Engine Block Serial Number Identification on this page. I haven't seen a serial number list that breaks lenses down by type only by the date on which the block of numbers was assigned. All like items within a given block may not have been made at the same time. One range for 50mm Summicrons, another range for 35mm Summilux, etc.Īnd one range for M2, another for M3. Why, meticulous Teutonic record-keeping, Richard! Also, it has been Leica's habit to assign a block of serial numbers at a time, to each product. Same question goes for the M-bodies as well - when there are multiple current bodies in production M6TTL, MP, M7 - do they all share the same serial number range? 'how was the consumption of these numbers managed to prevent duplicate numbers - or gaps in ranges.' Just curious in case anyone would happen to know. Were the serial numbers on Leica-brand lenses assigned across all lens types - or was it one serial number for Elmarit, Elmar, Summicron, etc, etc? If the same serial number range was used for all type of lenses produced at any given point in time (35, 50, summarit, 'cron, etc) - how was the consumption of these numbers managed to prevent duplicate numbers - or gaps in ranges - as the serial number is on a part of the lens that seems to be a part of the actual manufacturing of the lens. Is the aperture on new serial numbers of this lens still loose? Lens (Black) featuring Leica M-Mount Lens.
