Hi
A late friend told me that these were the bane of the life of someone in the trade and if it was a high volume item they would recut the die.
Low volume, rarely used dies would be banded with a heat shrunk ring to hold them together. Cracks were still evident on some items.
I think my spares has a bi-metal RWF/ Lancs or similar with a cut slider. I was told that this was a modification for when being worn with certain types of head dress.
When/if it surfaces, I'll post a photo of it!
