I'm on this already. I have NO plans to produce anything that might be in conflict here. I respect Singer (the old Singer at least) and want to help collectors, not "make a few bucks".
A couple of people have approached the Singer legal department and were soundly rebuffed. My plan is currently to be ABLE to produce a good reproduction, have the artwork, and production capability in place, and then approach Singer's marketing group about this opportunity, one which most of the work has already been done.
In a perfect world I would like to be part of helping some supplier be able to produce decals for Singer to offer directly on their site.
