Andy,welcome to the forum.
Machine s/n 932782 was despatched on 5-1-59 and delivered on 31-3-59 to A B Lowcook, Strathdean, Wilmslow Rd, Woodford, Cheshire; details from factory records. Drop me a pm with your e mail address and I can send an owners manual with parts list, there isn’t a workshop manual. The larger tyres will probably foul the reverse gear casing on the l/h side of the machine, OK if wheels are on wide setting but not good if on narrow setting. The original colour is an odd metalic hammerite sort of blue green. If you google Monro Tiller you should find my website which has photos of some of the machines in my collection and information about each model.
