Not just  ‘history’ books. But  Many books,
are,  re-written as to being, P.C.  Correct!

Case in point, (about just a very generic book),
Written first in 1965, by Frank Barns.
It was the MOST, comprehensive compilation, of “Cartridges Of The World”, Ever Written. It reflected Years of research.

It has been reproduced/re printed, 12 times.
Each time, the, ‘old’ stuff is still their, just, the ’new’ things have been added.

I have a 1969 copy, and a 2006 copy.
In the 69 one, the original Author, (now deceased)
In a description of a cartridge,  when fired in a certain brand/model of firearm, because of the shallow riffling, and slow twist, he said:
      “When fired in a wore out, Win 94,
        you can’t hit a FLOCK of Barnes,
        if you were standing inside one”

In 06, now changed to:
“ Much Ink has been spilled, claiming the .32 Special, won’t shoot after the barrel gets a bit of wear”.

Then goes on to say, how he shot a Different, Make/Model, (Chambered the same), and it shot just fine.
and Also, shot a  ‘Win 94’, and it shot just the same.
   YET,   NEGLECTED, to say,   was that firearm, made,   Before, or After 64.?
     (When Winchester had the Big Bankruptcy,
      and Dramatically changed, it’s manufacturing)
also, that rate of,  ’spin, twist’, and the depth of rifleing,  
CHANGES, as to, when/how/who, the firearms are  Manufactured by.

So, Many books, are subject to change,
    by JUST some, ‘P.C. Correct’, person.
        through Lies, by omission of Fact.

I Guess, some here, would consider a Statue of George Washington,
As being a Statue of a, ’traitor’.
 
   (After all he was, to the British)

But I wonder, WHY, His Statue, is in,
Trafalgar Square, in the UK ?????

  Could it be,   'Being, P.C.'  ??????
