Yes, this is a movie camera lens. Here is some info from the Vade Meccum:

Series 1 later was used for the Kinic f3.1 made over a long period in 1.625-3in for movie work and as a large portrait lens, and this is a much more typical product.
2in for movie

Kinic f3.5/20, 23/25mm and 50mm lenses for 16mm and 35mm use on a number of cameras, and also a faster series in f2.8/25mm, f2.7/25mm and f2.5/23 and 47mm. A very early f3.0/50mm was on a 1914 Williamson 35mm camera. There was also another series in f1.9 and also f1.5 and f1.4 post-WW2. These probably included Gauss and Kinic type designs.

Cooke Anastigmat (TeleKinic?) f4.5/150mm probably by 1930, as noted with the f2.6 in B.J.A. 1930, p364. However they are all actually named as "Cooke" as well as sometimes Kinic or Panchro which complicates things today.


16mm Cine
Kinic f1.5 1in =25mm Seen at No251,40x, blue coated, this seems to be a 16mm lens from the early postwar era. Here the designer was Warmisham, and as a f1.5 lens, it is a Petzval derivative of 1+2+i+1+1 layout. (App069)
Cooke f1.5 90mm This may be a Kinic but no name was given.
Kinic f2.8, 50mm; f2,5, 75mm These were in one 1960 2nd hand list.
