That's interesting! Now I'm considering to precautionarily remove the entire plaster core from my example, as the celluloid itself is still undamaged. The plaster is badly cast and brittle - the black spot visible on the foto is actually a hole caused by a bubble.
That's a tough call. Personally I would rather have the cylinder split rather than remove the core. I cannot play the cylinder but the original is all there and actually shows what happens over time. Such a pity that the split in this way. I had about 10 of the cylinders and they all split close to the same time.
