LOL. I asked a straightforward question. You apparently don't know the answer. So we get the usual CT commentary instead of answers. It seems pretty obvious that if Oswald carried the rifle in that bag (and he did) that it was dissembled if the assembled rifle is longer than the bag. I'm not sure why think that has to be "worked out." The question that I posed to you is what is meant by "dissembled" in this context. What is the fewest possible pieces that his rifle would be in to make it fit the bag? For example, could the barrel be removed from the stock and fit it in the bag? Only two large pieces rather than breaking the rifle completely down into multiple pieces. Far easier to carry the rifle in two large pieces than with multiple smaller pieces. And why folding it on one end constitutes some type of "security" issue for the contents is a mystifying concern. Anyone who carries a lunch bag just folds the top end and gravity does the rest. The contents don't fly out of the top to the moon. Same with Oswald's bag. He carries the folded end up and there is no problem.
Part of removal up to where the Barrel can be realeased from the stock.
Remove bolt.
Remove bayonet lug screw.
Remove bayonet lug.
Unscrew the sling (Front barrel band) bracket.
Remove wooden barrel cover.
Remove the 2 action screws for trigger guard.(This releases the barrel from the stock.)
And the opposite to re assemble. Hardly a simple operation especially without a screwdriver.
