I’ve only seen photos of one 8x30W unit #513, so again I’d also be eager to see photos of other specimens

(it's possible that they may have been so marked to comply with import restrictions that applied to various foreign goods after WWII?)Īll have 3 screws per body plate, indicating pre-1966 production (or perhaps more correctly that they made use of plates produced prior to 1966)Īs I’m not familiar with this model, I’d be particularly eager to see photos, especially ones showing the eyepieces and markings, and To my knowledge these comprised the Habicht-Tyrol, the Simplon and the Imperia However, there were also additional units specially marked - and numbered - for the UK market They were mainly marked Falke, but there were variations marked Habicht and/or Swarovski-Optik Tirol, as referred to in post #31, in A) above The units were all new post-WWII commercial production, and all that I’ve seen are CF While a somewhat cheaper alternative to the dual coated main product line, it was also probably a recognition that some buyers preferred a less yellow image similar to other binoculars Swarovski also offered single layer coating (the first layer of the DV coating) on some production from 1956 to 1968 * An exception was the 6x30 binoculars which were also offered uncoated until at least 1968! though at the cost of a significantly more yellow imageĪlong with my more recent thoughts in post #10 at: The dual layer coating was developed by Optics Balzers, and provided a distinct performance advantage over single coated binoculars However, all but the very earliest new commercial production in 1948 had the recognisable dual layer DV coating *ĭual layer coating continued on the traditional style Porro prism models until 1992, when it was replaced with Swarotop multi-coating

The image is from Frank (aka LPT on Bird Forum) at: Īll of Swarovski's WWII military production was uncoated, as were the post-WWII DWS marked units * See the image of a DWS unit to compare to the images provided by Jan van Daalen in post #21 in the link attached to A) above The former were mainly sold to Allied occupation forces, and the later were primarily for export all new production as referred to in A) above (perhaps 10,000 units in all: the observed numbering is from 169,934 to 178,434, which continued on from the first cag numbering sequence that went to at least 168,651), and sold slightly modified cag units which were marked DWS * When Swarovski was able to officially recommence binocular production/ commence commercial sales in 1948, they: See slide #18 in Gijs’ Power Point presentation ‘History and quality development of Swarovski Optik 1935-present time’ at: įollowing the end of the war, in late 1945 Swarovski recommenced spectacle lens production, and also established the ‘Vocational School for Opticians’ locally in Solbad HallĪfter the war years there would have been a large civilian demand for such a product * In late April 1945 Swarovski had on hand an order for 5,000 Dienstglas that were still being worked onĪs the formal German surrender was on 7th May, this additional production would have formed a substantial part of the post-WWII DWS marked units See Ken Tomon’s comprehensive coverage at: Production exceeded 4,000 units which were also marked cag It was a 1.5x11mm intermediate eye relief telescopic sight For convenience, I’ve sorted the information both chronologically and by featuresĪdditionally, in 1943 Swarovski also manufactured another product, the ZF 41/1. Various on-line posts indicate that Swarovski produced around 18% of the total 6x30’s (However, I’ve not seen any indication as to the source of the information)Īnd for a lot more detail see the two attached tables.

The units were marked with the three letter code 'cag' to identify them as Swarovski production Production was from April 1941 to around late-1944, with around 183,000 units delivered to the military * the military version of the Zeiss Silvarem IF binocular The main product was the standard pattern 6x30 Dienstglas i.e. However during the war, production was entirely devoted to military needs In 1939 it established an optics department and commenced to manufacture spectacle lens blanks Prior to WWII Swarovski did not make binoculars but specialised in making crystals for the jewellery trade
