I found this programme for the Grimsby & District Round Table Traction Engine Rally 1963 in a box of photos. It was held on Waltham Aerodrome which was just over our back garden wall. I do remember going to see traction engines when I was young but didn’t think of it as “just over the wall” – perhaps that’s because we had to drive round to the proper entrance. I thought it worth sharing so I have scanned it and made a PDF file from it.
Inside front cover – 100 octane fuel 4sh 8 1/2d. Approximately 24p per gallon (just over 5p per litre) with plenty of lead to go with it too. Fill your tank for less than £3.
