1917 GE AUU S6 six wing. Bought from original owners family, perfect time capsule. Does run well on all speeds, BUT! I do not use often due to all original wiring. This is a fragile collectors piece at this point in its life… As always with a antique collectors item they can be inherently dangerous! Plug in/attempt use at your own risk! As-is, as-shown no warrantee’s expressed or implied.
