I hope I am starting some controversy over this one...a U-866 small 2 skirter measuring 4 3/4 x 6 1/2 x 4 3/8 high. All that have been seen in blue are no-names. Collectors seem to call it a JD..and it looks like one but Locke also made some mud in this color glaze and the Locke blue is really more of a "powder blue" color, like this one. I have seen some brown Locke U-866's just like this (currently not listed in the guide). Again, it does look similar to a JD (Jeffery-DeWitt) blue but, they tended to stamp their JD and the year made on almost everything. I am calling it a Locke U-866, but it could be a JD, so there! ;)
