Congratulations on finding this fine W&W and the work you did on it. The No. 8 is my favorite machine aesthetically; I like its no-nonsense but pleasing design. Miller will enjoy seeing it, I'm sure. (Say "hello" to him from me - I don't get out much these days.)
Question about the bobbin-access plate (wood) to the left of the needle plate. Does it look original or is it a replacement? I ask because mine has a little scoop cut out of it for easy removal. The wood seems to match pretty well; maybe it's a pre-scoop design?
