I am hoping Brian or Newscottlander will shime in with the correct info.
Your type2 mag. catch with short face with serrations was very limited in production or modified type1's.

I would like the correct info when Inland switched from type1 safties to type2, and when they switched from type1A long smooth face mag. catch to type2A short smooth face.

The only info I have is what I wrote down from original carbines, the first one might be yours, but I do not remember where I got it.

96XXX with type1 safety and type2 catch.
124XXX with type1 safety and type 1A catch.
186XXX with type2 safety and type2A catch.
204XXX with type2 safety and type2A catch, which is my original Inland.
225XXX with type1 safety and type2A catch.
242XXX with type1 safety and type2A catch.
258XXX with type2 safety and type2A catch.

As fars as I know the above carbines are original and not restored.
