"T" things that shouldn't exist

[Seaforth72]

If it is a British WWII manufacturer's code, M.16 was Bullers Ltd.,Tipton, Staff.

I've never seen a 1944 dated BSA 'T' that has a split foresight block.

Mind you that's only a few dozen....

My other 1945 dated BSA 'T' has a split front sight block.

My Brit 'T's are pretty evenly split between brass and zinc butt plates.

My Long Branch 'T's are split between steel and zinc.

Any idea who or what "M/16" was?
