You may try using one from the m1950 stove. Old Coleman Parts > Stove Parts > M1950 Burner Bowl - E19
@HercL4D2 thank you. It seems a good alternative indeed. I wonder which kind of material is this plate ? Steel ? It appears not to be brass.
I have another question : in my Aladdin, the pip is inserted in a part which appears not to be the original one. Please see photo. The stove works nicely but I would prefer to have the original part.
