I was able to resist those MOP grips, but I did get a spare barrel+extension for a caliber change [probably 7.65 Parabellum]...I won't bother with a full-profile pic, as it looks like any other Type 14 barrel...With one small exception...

If you look at the first pic, you'll see 'receiver' rear ends with the locking block 'ears'...689 is my T14; 203 is a used pull...Look at the red circles...The 689 'receiver' is relieved to let the locking block rotate up to clear the 'receiver' recess...The 203/spare isn't...

The spare won't let the locking block move up into battery...It won't even go into the 'receiver'...The red lines show the locking block in full retracted position; the spare is stopped by the rounded edge shown in the red circle...

Now, removing this metal to let the locking block retract is easily done...But...Looking close [see the second pic], I noticed an awful lot of *filework* in this area...Not just the edge of the 'receiver', but the inside edges of the locking block 'ears'...Crude, coarse filework...Hasty...Unskilled...

It's present on both of my 'receivers'...And is really mind boggling to think that this is part of the Nambu assembly line...Some slave labor peasant girl, squatting down on her clogs, 16 or 18 hours a day, filing the sharp edges of just each 'receiver' ear...I don't see any other obvious filing anywhere else...

The sides of the locking block that rotates are cut with a radius-ended end mill, and presumably filing/chamfering the edges of the 'ears' is the easiest way to make them clear the radiused cut...Without any complicated milling...A peasant girl with a file being cheaper than a milling operation...

I would be interested to see other T14 'receiver ear' pics...Does yours show crude filing???

Lugers have just as much intricate cavities/sliding parts, and they don't show file marks this crude...

There are many different engineers involved in a manufacturing process...This would be comical if it was Khyber Arms...But this is an Imperial Arsenal...In 1943...Not even yet the height of the war...
