I added the aftermarket Chinese hand crank to this machine. One bobbin and one bobbin case.The serial number does not come up with the right machine when I look up the number, G9041171. The lists that I have looked at say it is a 115 and it is definitely not that. The head on this machine is also smaller than similar machines I have had. You can see in the photos that the faceplate is overhangs the head and the thread tensioner sticks out further than other 27s I have seen. If anyone knows please let me know.
