Unfortunately Morgan front discs are Morgan specific, they are not used on anything else.
As supplied by the factory the castings are very green.
We have a lot of problems on the "production" racecars with the discs warping after they are used a few times in anger. However, once this has happened they can be skimmed true, and then seem to pretty much last forever.
All that said, I don't believe the discs are warping, but it is more likely they are suffering from pad pickup or pad shadowing on the discs after being used infrequently.
You can bead blast the discs to remove this pad contamination, but it will come back if the car continues to be used in a similar fashion.
Pad material can and will make a difference (I really don't rate EBC pads at all), as some are more susceptible to this than others
Most common pad materials used these days are designed to stop 1500 odd kg of heavily servo assisted daily driver
A light car like a 4/4 just doesn't use the material hard enough
