It is the perfect size case to put in a coat pocket with not too much of a bulge.
I also found a Briar Pipe Makers in London Directory on Pipedia. https://pipedia.org/wiki/Briar_Pipe_Makers_in_London_Directories. It read as follows: Now I had some idea of the age and provenance of the pipe in my hands.(He took photos of the case and the pipe before he cleaned it up.)The plush red lining covered entire inside of the case.While it was worn and a little soiled it still showed some of its original glory.The debris flowing out of the end of the tenon is also visible in this photo.The stem was a bit of a wreck with tooth chatter, tooth marks and nicks all around the top and underside.It was worn on the right side of the shield but it was very clear.
