Patricia Catchpole's Riding School on West Mersea beach.

A similar picture appeared in Essex County Standard:
"A picturesque part of the West Mersea scene since 1948 has been the string of horses from Miss Patricia Catchpole's riding school seen here cantering along the beach. From a modest start with two ponies bought for £50 the school now has 22 horses and caters for over 400 pupils a year. Although the popularity of riding is growing rapidly, costs are also going up steeply an in Miss Catchpole's experience are now over four times what they were when she started. A sign of affluence is that the young pupils now come from very type of background.

Anne Watson says: "Riding next to Catchy who is on Russet is Beverley Ransome on Helga, which belonged to Mary Jones, Firs Road. Maddy Candy on Flicka, then right to left, Simon Moore Brown on Jester, Seaview Ave, Lofty but not sure of rider, Michele Burton on Micky.
Flicka went on to spend her later years with Louis Dawson, East Mersea Road and lived to a great age. Beverley and Maddy came every week during the summer months, I think their parents had caravans somewhere.
