Those disks are probably 16-2/3 RPM, which is 50% of 33-1/3. So you can transfer them at 33, and then use the "change speed" function in your audio edior program to double the speed.

The more critical problem might be finding the correct stylus width. If they are indeed vinyl, it's unlikely that they date back to the 1920's. More likely from the 1950s or 1960s. If it was me, I would start with a microgroove (LP) stylus, and if that doesn't work well, go to a 78-type stylus.
