Luckily I have completed the assignment you gave us.
Thanks,
fixitfred!! Is this correct arrangement?
A - 1.265"
B - 0.243"
C - 0.481"
D - 0.522"
E - 0.854"
F - 0.932"
G - 1.841"
H - 0.794"
I - 0.211"
J - 0.468"
K - 1.894"
This is super weird. Those numbers differ too much from what I inferred from photos/schemas. For example I have:
A - 20.7 mm (0.815") - difference ~10 mm
F - 13 mm (0.512") - difference ~10 mm
K - 32 mm (1.26") - difference ~16 mm
With this in mind I can assume either I did not arrange numbers correctly or you measured Beretta 92 FS (I'm just guessing).
