I wish I did. Years ago when I got married my father and myself took down my layout carefully putting all my Lionel trains and accessories in their original boxes for storage in my parents home.
A number of years later I decided to build another layout, this time in my home together with my two sons. I called my dad to inform him I was coming for my train, and when I looked in the storage area they were gone! My father had no idea where they were so I called my younger brother. He informed me an elderly neighbor asked if he had any old toys to get rid of, that he would take them to an outdoor flea market and make him a bunch of money. My trains were sold and my brother received $20. 00 which at that time may have been a couple tanks of gas. Sad story , however there is not much you can say. He was my only brother.
