Wow, Conwy Borough, that takes me back to when I had just started senior school in Llandudno in the 60s. When they were called Borough United, they actually won the Welsh Cup, probably in 1963, which was quite a shock and then represented Wales in European Cup Winners Cup the following season when they actually did a bit better than expected. One of their midfielders, Dyfed Elias, was one of my teachers and became a bit of a school hero for a while. A few years later, he coached the junior team I played for and changed me from a right winger into what would today probably be called a #10.
Meanwhile, back on topic, yes, an extraordinary kit!
