Any of you legal beagles can correct me, but my understanding of copyright practice is that for non-commercial purposes (and I suspect you’re not making any money on presentations to your Model A Club), as long as the original drawing is not modified (especially by not removing the name at the bottom) you should be able to use it with no problem. Just don’t state or imply that you created the drawing. That’s been my practice over the years as I am happy to give credit to the many talented folks out there. Including you!
