Philippe, le Vade Mecum dit:
"BisTelar This was important as the first telephoto to be designed and made with fixed separation of the glasses, allowing better corrections by the designer K.Martin in 1905. It was developed in successive designs and is a fairly easy lens to find as it sold well.
Bistelar Series 1 f9.0 It was made in 7, 10, 12, (1911) 14in later. use 10in for 5x4. from 1905.(R) Layout Bu007, gives 1.65x the image size expected for extension. (B.J.A. 1907, p869) It was sold from 1905, and in two magnifications, ie ? as below. It is not in H&D's list in 1939, or Frerk's 1926 list."
Je crois que le votre est un Serie I, focal 14 pouces.
