I am about to make up a set of CAD drawings for the glass presser foot of my no.3.? I notice that the needle hole in it is offset, i.e., it does not lie on the lateral center line of the insert. Rather, it is closer to the far edge. Yet I see in some images of other nos.1-3 that the needle hole appears to be centered.? Am I correct on this?? Did the location of the needle hole, and therefore I presume the needle itself, change over time?? Do we have any information as to when that change took place?? Thanks for any help.
