The flap was glued only at the top so it would still open and close, the buttplate was from a M1 rifle
I wish I had a picture to post of the T44E5 Butt Plate. The BAR flap was fitting perfectly within the Garand Butt Plate and was welded on beautifully.
When I was moving from NJ to Pa., I brought a bunch of rare stuff to the OGCA show to raise money on a down payment for the house. I ran into a Doctor from Ohio who had SA Inc make him a full auto receiver marked T44E5. He purchased the stock complete from me. He was very happy because it was the last item he needed.
The stock was very different. It had a different liner, a different front swivel and was wider. The Butt Plate was an incredible make up by SA (Real SA).
