Two pancake pans (Wymondham NR18)

I've two pancake pans that would work on gas and electric stoves but not on induction.
These have been well used, with no scratches on the surface and perfectly good, but we recently changed to induction and they unfortunately don't work on that.

They need to be washed by hand only, not in the dishwasher, as that affects the surface in the long run.
