You can tell the age of tree by counting its rings. For a wargamer it's a bit harder. For me I know I was gaming by August 1969 because I still have the first magazine I bought from Teddington Model Supplies.
And a closer look at the date.
The next issue had one of my favourite covers and certainly helped kick of my ACW Airfix collection.
With adverts like this it was not long before I ventured North of the River buy Hinton Hunt figures from Camden Passage near the Angel Islington.
