Did Parker Hale use ba threads.

[Alpha1]

As the title suggests I'm interested to know if Alfred J Parker used ba cap head screws on there rear sights. Did they use ba threads to attach the sights to the rear of the action. As you probably guessed I have been trying to identify a thread and its proving difficult I think its 4ba but I'm not sure.

Thank you very much 1066 it looks like I was right it is 4BA. That makes life a lot easier. I just need to raid the tap and die cabinet at work now.
