Old, vintage Voigtlander camera - folding, lenses... : history, ideas 1896-1972

Description: I offer here a large collection of more than 430 (!) old patent specifications of the world-famous German company Voigtländer (Voigtlander), which were published between 1896 (!) and 1972 in the USA and Great Britain. All patents are complete, that means contain the full text and all (often very detailed - see example) drawings. Patent documents are all in English and mainly deal with various cameras (folding camera, roll film camera...) or lens technology (Heliar, Dynar, Oxyn) or parts thereof .The collection I have compiled is the world's most comprehensive patent overview of this company's technology. Delivery is as pdf file (*.pdf) collection on a CD (not as printed book!). For viewing and printing you need only the wellknown Acrobat Reader or a similar pdf reader. Each file contains one complete p a t e n t. Also included is an Excel (*.xls - file) list with patent numbers, datas of issue, inventor name and patent titles. This list is linked directly to the patent files so that each patent will be open easily if you click on the link. It is not really a problem if you do not have the programme Excel from Microsoft. Look for "Excel Viewer" at google and you will find freeware version of anExcel Viewer programme. So you can open and print the Excel table without problem! Of course you can open (and also print) each patent file also direct without using of the Excel table!! Copyright of the CD has only the seller!Shipping worldwide as airmail letter.
