The 1962 " No 2 " is not quite the same gun as we know today . It is my understanding that it was designated Model 2 as opposed to No 2 .There have been quite a few changes since this gun was built and the current No 2 parts will[largely] not be the same.Specifically locks and ejector work/extractors.
That said the over all quality was generally good and I do see many of these older guns still in regular use and in good over all condition .
