I have a rebuilt Singer 27 that was painted with a paint brush, but it wasn’t done by Great Eastern. I don’t know who did it. There is paint inside the casting where the bristles wrapped around the edge in places. The inspection covers preserved the paint complete with brush streaks like it had been painted recently, but it was most likely done back in the 1940s. It also has the BW lobe removed, BW moved up onto the belt guard, Singer Badge removed, and a small balance wheel.
Looks like you’ve got most of a later (Style 11?) Singer Puzzle Box Attachment Kit there, with a couple of extra feet in it.
