Hi,
All guess work without the certificates, but it looks like your Walter John PIKE may have come from Bristol. Just had a look, there is a Walter John PIKE on the 1939 register with his wife, Marina C. and son, Roderick J. By this Walter was born 18 June 1905 and was a Postman.
I took a look in the marriages and a Walter John PIKE did marry a Marina Cissie GARDNER in 1930 in Frome, Somerset (her parish, born 1910). Then in 1948 a Walter John PIKE married an Iris PAYNE in Frome, Somerset.
Without certificates there is no telling if its the same Walter. The only Walter PIKE on the Birth index and of the same month/year was in Bristol.
I hope this helps,
L.
