if your hand crank is a Chinese (PRC) version could you take a photo that is similar to the original singer photo above?
On the new hand cranks I've gotten, the body is cast in one piece. I've had the same thought about mounting a crank on an old head without the boss. Simplest thing I could think of was casting or machining a boss, attaching it to the head and then attaching crank to the boss. Project wasn't feasible for me because I have a bunch of Singers waiting for a hand crank with bosses factory applied but the idea I find very interesting.
