You lucky person you!! A fantastic find of a very rare piece. I 've been collecting Bagley for many years and was lucky enough to obtain this set, but it is the only one I have seen. Even the Bagley book by Angela , Derek and Betty Parsons illustrates only a part set. I have tried to attached a photo of my set to show the size of the small troughs, but cannot make the file small enough (Any suggestions gladly received)[I think I may have done it!]. They actually measure about 8 by 3 cm each. Good luck finding these (that was not meant to sound sarcastic!)
