I have a Laurel & Hardy Super 8 sound print "Any Old Port" I bought on EBAY that unfortunately has the soundtrack completely erased. The person I bought it from refunded all my money and stated I could keep the film.

My question is: Has anyone been in a similar situation? If I were to acquire another sound print of "Any Old Port" ... is there a way to add the soundtrack of the good print onto the erased print in sync?

I have 4 sound projectors: Elmo ST1200-HD; Elmo ST1200-D; Elmo ST-180 and a Eumig 710D.

Can anyone help and advise me on this?

It can be done with the ST's, you will have to make sure they both play at the same speed.

I haven't been there, but it can happen if we put our reel right on the top of strong magnetic field (such as speaker) and all sound recorded on the magnetic stripe will go forever! (get erased)

Hi, yes it can be done, nominally via synching up two projectors. I've used an ELMO ST-600 as the playback projector and the ELMO GS-1200 as the recording projector. The playback projector has to have an output signal which can be DIYed via installing a Reed Switch that clicks once per rotation the main shaft, thus a once per frame signal. The GS-1200 then slaves itself to the playback projector via its ESS switching circuitry. What might be easier, although will take a few tries, is to just find a video of the movie, edit the audio portion out to 'fit' the Super 8mm film's length, and then manually re-record this to back onto the film. If not doing any editing, the simplest method is to just line things up, record the various segments as best as you're able to. Using the instant on record button on some model projectors, and the footage counter, and paying strict attention to the sound and images, it can be done. I have seen some use reel-to-reel methods.....and drag a finger on the supply reel to regulate the audio so it stays in visual synch with the new recording onto the film as it's recording, or using a variable speed tape recorder and riding the speed control. This means having to record the audio portions from the video of the film onto a tape format first. Anyhow, I did this some years back after sound striping some silent Digests, on which I wanted the sound. Good luck!
