Newtown jersey design changed in 1976 that added the three stripes onto the sleeves, so this jersey is from before that period. However, it’s difficult to narrow down this jersey to an exact season as the design hadn’t changed from the early 60's but looking at the material and the number plus the way the badge is sewn together with heavy duty plastic. I've estimated that this jersey is from just before the jersey was modified with the three stripes, in reality though it's pretty much impossible to pin this down to a particular year. I picked this up from an internet auction site many years ago, was happy overall with the condition, just a shame that a previous owner cut the sleeves short. There's no manufacturer details available as the tag has been worn away over the years.
