The Bluegrass Railroad Museum has had this caboose for many years. It is former-Monon wide-vision caboose # 81526. It came to the musuem from the Clinchfield Railroad and was their #1065 (see attached photo). Prior to being owned by CRR, the caboose was lettered L&N numbers 917, 6917 and 6491.
The Monon Society has tried to purchase this caboose over the years. At one time the price was reasonable, but other logistics prevented that from happenng. Eventually, BGRM decided to spend the money for full restoration, but the last time I saw it and took photos, it was being used as a storage barn for a large amount of railroad hardware. It's possible they have now placed it in railfan service.
