1:33 "full" usually means the full area of the film between sprockets including the area in which the soundtrack is now printed, it is the original silent film ratio. Academy Ratio is 1:37 which has a slightly thicker black mask between frames at the top and bottom. From the sounds of it your film is what is known as Movietone ratio. And yes the solution is to use the scope aperture plates with (usually) a different lens so that the picture is small enough to fit on the screen. You will be most certainly depending on the ingenuity and insight of the projectionist, and the support of the institution or theatre for which they are projecting.

Thanks for the response. I does sound like I would have to rely on the ingenuity of projectionists to make sure my film was properly presented. My "1:33 full" is a little different that the print you describe since it does not have the black bars top and bottom but goes all the way to the "thin" frame line.
From what I understand even the thinness of these frame lines has many variations, over and above the obvious black bars you mention.

The other question is whether today's venues can show full aperture silent 35mm? (which I believe is equivalent to today's "Super 35mm" format --not usually meant for projection as is.)

We ran Eric Rhomer's "L'Amour D'Astre et Celadon" last night in our cinema. The film was made a couple of years ago in 1:1.33 (blow up from std 16mm). It had been printed at thought it was 1:1.85 with black bars up the side as well as top and bottom which i'd never seen done before. It is a neat solution. We have no 1.33 aperture but with the scope apeture (which is taller than 1:33) and the right lens and proper screen masking it's really the same thing. I would have thought festival venues and venues used to showing old films and art films should have no trouble at all as long as they're made aware of the aspect in advance.

It's a great film if you the chance to see it.

A regular scope aperture plate with a flat lens would theoretically give you about 1:1.18 which might be close enough. You would still need a longer lens (or perhaps a zoom attachment that can reduce) to fit the frame vertically in the screen.
