Blimey Ulrich, I'd completely given up on getting a reply -
thank you! Of course, it would be even better to ask for the source or restoration too, due to the varying nature of so many silent film transfers. That would be of use with many transfers of later sound films too. But then, the form would be in danger of becoming too lengthy and unwieldy. Ideally, there'd be a separate, tailored form for silents, but this soundtrack addition, along with the runtime, should enable IDing most of the transfers.
