I thought I'd post this design as it hasn't been mentioned for a while. It has Grace Darling written across the stern viewable from the outside, and inside the Rd.No.23527. I couldn't find this number anywhere but from previous posts apparently it's the Rd.No. for the name of the piece. The number for the actual design is 39414 which was registered by Edward Bolton

on 11/12/1885. The other number was registered on 11/3/1885. Some pieces have both numbers.
