Differential Manifolds – Antoni A. Kosinski – Google Books
In his section on connect sums, Kosinski does not seem to acknowledge that, in the case where the manifolds in question do not admit orientation reversing diffeomorphisms, the topology in fact homotopy type of a connect sum of two smooth manifolds may depend on the particular identification of spheres used to connect the manifolds. His definition of connect sum is as follows.
The mistake in the proof seems to come at the bottom of page 91 when he claims: Later on page 95 he claims in Theorem 2. An orientation reversing differeomorphism of the real line which we use to induce an orientation reversing differeomorphism of the Euclidean space minus a point.
I disagree that Kosinski’s book kosunski solid though. So if you feel really confused you should consult other sources or even the original paper in some of the topics.

Yes but as I read theorem 3. Maybe I’m misreading or misunderstanding.
