Yet despite his age and a complete lack of senior experience George was both a rapid and long-term rapid success. St. Mirren having struggled even with Summers finished safely mid-table. The new boy would stay at Love Street for six seasons, a double century of starts and win three caps. In fact he might have stayed longer but for financial pressures pushing the club to sell him on. Thus it was that at still only just twenty-four he was on his way to Notts County. However, despite being made captain, it was a move that would have been better for him had it been elsewhere. The Midlands team was Second Division and even then struggling. Indeed the following season, 1934-5, it was relegated to the English Third Division South, at which point Walker became rather stuck in this lowest tier during what should have been his best years, not improved in 1936 when he moved sideways to Crystal Palace for three seasons and then in 1939, sideways once more, to Watford. 

With the War he served in the RAF. However, post-War it all becomes somewhat obscure. Uncle Alex had died during the the First World War but of tuberculosis. Uncle Bobby would die in 1930 in Edinburgh. Both are buried in Edinburgh's North Merchiston Cemetery with their mother. But of George Snr. there is little or nothing except that he and his wife, Mary, George Jnr.'s mother, seemed to have moved to Paisley, where they both died, he in 1950, she in 1961. And that her death was in fact signed off by George Jnr., who is said at the time to be living not in Yorkshire but Ralston, which is by Paisley. Apart from that nothing more is know just now, not even if George Jnr. married and had children.
