If you would, measure inside to inside on the front chisel marks - that is, determine the minimum distance between left and right "disturbances" to base metal.

I don't have flip sight dimensioned drawings, but I do have a flip by another maker to measure. So, do a blind taste test, report the findings, and if nobody else has an IBM appropriate flip to measure, I'll whip out the calipers.
If it's too small or way too big for a flip sight, that's one thing. If it's about right, the question kinda answers itself.

Inside to inside chisel to chisel marks is about 1.30cm

inside left punch mark to right side chisel mark is 1.20cm.
