I was moving several pieces around today, such as a 252, 253 259 and 249 locos along with 600 series passenger cars and a ZW transformer. When I was done I found this laying on the carpet. Not sure if this insulator came from one of these or not. Looked the best I could and didn’t see any logical location. Maybe it was a hitch hiker picked up along the way over the years any just finally got off. Thanks in advance for your help.
Thank you FIXIT...that explains it.
