What Constitutes a Transfer under the National Firearms Act

Section 479.11
of the National Firearms Act defines a Transfer as:  This term and the various derivatives thereof shall include selling, assigning, pledging, leasing, loaning, giving away, or
otherwise disposing of.

There seems to be much confusion over the violations of the National Firearms Act over this term because the typical legal definition of transfer involves a change in the possession and / or legal title of; convey.

There is clearly a significant difference in how the NFA defines the term Transfer.
