Hi Tony, sorry I cannot identify exactly but I can narrow it down.
Its NOT 628a, 1929, 915 1932, 915a 1933, 915b 1934, 1388 1936, 1670 1938/39
Amongst these examples the sheer number of dealers was greatest in 1936 and declined in 1938,
so my best guess is your booklet is 1935 915C or 1937 1388A.
There are only about 1/4 of a page of dealers after woodford green so you probably have the lot. cheers Russell
