About one year ago my grandfather died of cancer. Now my grandmother lives alone and got rid of most of his things over time including a model railway.
As a child, I spent many hours at my grandparents, building it together with my grandfather. Some of the parts we used, were gifted to me on birthdays or christmas. As I grew older, I lost interest in it and my grandfather expanded the railway from time to time on his own.
After grandpa died, my grandma told me, she would sell the whole model railway (about 3000€ worth) and would give me the money (or some of it, I don't remember). I took one engine as a memory. Now I haven't heard about it since then. I only saw my uncle posting an advertisement to sell the model railway on facebook about two months ago.
My family has a lot of money because of a firm my grandfather founded, which is now managed by my father and said uncle. I personally don't have any financial problems, but am not living an extra-ordinary live either.
Now, how do I talk to my grandma about the money, she promised me? I don't want to come off as spoiled, as my grandma already gives financial support to me every month and very generous gifts on birthdays and christmas holidays (among other things).
