For sale is a U-2260 NN (THOMAS), it has a single BJS. It also has 2021 written on top. Sounds like there are 1 or 2 others known. Elton Gish said 2021 was the catalog number for this skirt, 1907-1917, thanks Elton. Following pictures will show 2021 up close and the flakes/chips to bottom edge of top skirt. $100 shipped. Thank you!
