I am a Pimm researcher. Recently on the U+Yesterday Channel 27 (Incorrect) on the footage detective there was a clip about the bustling market in the Bullring. In the clip they showedin the background a shop called Pimms which I believe was a pet shop. Is the owner of the shop family related to the Midland etcher Joseph Frank Pimm (1900-1970) who did many sketches in the Birmingham area. You can see his works online. If so I have a family tree made up of this family.
Correction - The channel is 82 on Freeview called Talking Pictures. The programme is called the Footage Detective and was broadcast on Sunday the 26th of October at 1700. If you go on the Talking Picture site you can see the programme again
