I had the same experience with new b/w poly prints during my time in the booth in the late '90s - when unpicking splicing tape, it would often take a chunk of emulsion with it. This didn't seem to affect elements which had been printed in the '80s or earlier, or any acetate prints as far as I can remember.

Only with b/w prints? This print was definately triacetate, not polyester, and there was no hint of vinegar. I'm certain about that because the first thing I do when I get a print of a film this old is to make absolutely certain that we haven't been sent a nitrate print in error. It's very unlikely, but I always check. If it was indeed a 50th anniversary print, then that would tie in with what others have said about problems with '90s prints. I suppose that I haven't had many b/w prints of that vintage through my hands; plenty of older ones, and, recently, several newish ones on polyester.

I remember that there was speculation that there might be problems with emulsion peeling from polyester, but, from the 1960s, Prinz and Ferrania Super-8 films were on a polyester base, as was Fuji Single-8 film. I've got a few reels of each of these, and while they show more fading than the Triacetate Kodachrome from the same period, I've had no problems with the emulsion peeling.

If there are any theatres in Ireland which are equipped and certified to run nitrate, do try and show the BFI's nitrate print of Man of Aran. I saw it at the NFT many years ago, and can't remember any other 35mm b/w print that comes anywhere near it for sharpness and tonal range.

I doubt if you'll find anywhere that's still got a nitrate licence, but even if you could, would the BFI let a nitrate print out to a cinema? Also, how much would it cost to transport the thing, and how much paperwork would be required? I've seen some very good nitrate prints in the past, but it's just about impossible to see them today.

TNT will ship nitrate for the same price as other films; but delivery can take a very long time, because they leave your consignment in a depot until such time as a refrigerated lorry or van is going where you want it taken. 3-4 weeks from Middlesbrough to London is not unusual. If there's no hurry, fine; if there is, I'll stick the films in a carrier bag and hop on the Easyjet with them (only joking - I'd actually drive).

Here is the edge damage which is not repairable by "Perf-Fix" machine.

You will note that the sound track is damaged and the right channel would be very noisy if played back. Also the film will not be centered on the scanner since there is no reference edge.

The perf fix will repair the missing sprocket holes but the film still is unplayable as mentioned. Simplex XL and SH-1000 sound reader w/Kelmar red conversion.

You still have one good side of perfs left! No problem! I've run lots of films with one sided perf damage through Century C's and JJ, and a Pro 35. [thumbsup]

Sorry Leo, but unfortunately there are no such equipped cinemas here. Nice thought though, and I'd love to see the nitrate version myself. It is a great documentary classic.

Kenneth - a Norelco AAII would run that film without any problems - tho' I'd still keep an eye on it!

Film with major perf damage should run okay through Norelcos and Century C - from my own experience.
