To answer the question re the grounds layout - ive already spoken with Gary James on Twitter, here's what he had to say:
" Very important that layout of Maine Rd. It is accurate for 1934 & shows the corner Platt Lane roof on plan. In 1935 the rest of Platt Lane was roofed, so ground was like that between 1931-35. This is exactly as it was when 84,569 attended record crowd game in March 1934. You've picked the right plan/year. Good luck with it."
