I've spotted this trough many times coming in and out of Bath, so I decided to take a wander out to find out about it.
The below is the listing description.
Standard granite trough as used by the Metropolitan Cattle Trough and Drinking Fountain Association in London. Top trough with gabled water inlet at one end with a drinking fountain on back. Trough supported on two solid legs protected from cartwheels by half round bollards. Lower troughs for dogs. Inscription : ERECTED BY MAJOR BRICKMANN JP 1906 ALDERMAN OF THE CITY OF BATH.
The Cache can be done as a cache and dash or you can park at Alice Park car park and combine with GC56B6Y Going Round the Bend, GC4EA6M River Avon Walk and GC6X6VZ A Fine Pair #736.
