This remarkably sturdy projector was updated in the 1960's with stereo capabilities. The transport system is relatively jiggle free, as was necessary where the intended screen size was 25' or more. Unfortunately, it turned out that no lab was willing or able to come up with an equally precise 16mm printing method. Projects to place this machine in commercial houses were abandoned and the Model 25 was consigned to use on college campuses and other non-theatrical applications. In 1988 another attempt to resurect commercial 16mm developed at AMC theaters. The Model 25 was updated to the Model 40 but again the idea failed for lack of good lab prints and the inability of managers and ushers to operate the unusual machine.
