In the first few years on the Pipe Trades wore purple and gold dureen (cotton with nylon or rayon) sweaters. Have one badly faded team photo and one personal pic. Back when I started playing organized hockey some games in the Westfort League were played on outdoor arenas and some on indoor arenas. We usually didn't get to keep the sweaters back then; they were used year after year.
For my final year with the Pipe Trades team we changed to a red polyester jersey. I believe I was #6 that year. Here's another team pic and personal from the 1977-78 season. I am in the top left corner next to my dad who was one of the coaches that year. Both pictures were very likely taken at Delaney Arena.

Got some photos from Kevin Wright of the Pipe Trades. A couple team photos and the sweater he has.
