2Psteel6, Where did that information come from? I have serious doubts pistols would be rebuilt as their Government has for many years if there was a supply of unused arms that could be put into service at no cost.
I found it on another forum, perhaps 1911forum.com? The poster was a Canadian and had a pic of a new-in-wrap Inglis wth an intact lend-lease decal. Seemed knowledgeable, and from what I know of military procurement, it sounded reasonable that they'd keep a certain number in reserve.
I'd assume that once a military unit takes a piece of equipment into its property book, it stays there come hell or high water; the unit manages its FTRs through the armorer. New, reserve pistols wouldn't be shipped to that unit until the original ones were totally unserviceable after several FTRs.
That's how it works in our army, anyway. The army is full of junked M9s, but there are still a bunch of centrally stored ones too. That's why it sounded reasonable to me.
I'll try to find the post.
