Florence Crown machine
 

Bought this yesterday! From what I can tell it is a Crown and came with a cool coffin top. The previous owners bought the machine and treadle at a yard sale from the grandson of the original owner. They turned the treadle into a table stand and didnt want the machine or coffin top. I will need to make a base for it. The number on the plate is 195931 with several patent years listed around 1871. I can not find much information on this machine to accurately date it. Cool though! Is there any possible way to turn this into a hand crank?

Did it come with a shuttle and bobbins? I like the leaf tension.You won't be very likely to find a hand crank for it.

Yes, bobbin and shuttle intact!
