double flap baseball helmets question

[deburton]

Hi. I recently purchased a 1983 Portland Beavers game used helmet on Ebay. It was sold as a Len Matuszek game used helmet. It is a single flap helmet made for a left handed batter. That part all checks out, but I had a very knowledgeable friend in the hobby tell me that 1983 was the first year that MLB mandated that the minor leagues use only double flap helmets and that the one I just got doesn't seem to be authentic. He suggested that I pose this question to the GUU world to get more feedback.
I have a few pictures that are posted on "May pickups" but don't have a picture of the single flap.
If you have any knowledge that you can share with me , I would appreciate it.
Thanks, David

I am always looking for game used Portland Beavers items , Portland Mavericks items and occasionally, Jay Buhner items.

If a player played in the MLB prior to 1983 ( the year double flaps in the minors and single flaps in MLB were mandated) they were able to continue using the flapless helmets.

Matuszek played with the Phils in 81 and 82 so he would have been exempt from the flap helmets and perhaps chose to use the single flaps in the minors.

MLBers who played in the minors were allowed to follow MLB rules which would have allowed him to use a single flap helmet.

Here's a photo of David Wright when he was rehabbing in the minors wearing his single flap Mets helmet.
