Hi...I just found this site. My mother-in-law passed away a few years ago and she had a Modernage Super De Luxe Precision sewing machine which was given to me. I did not receive an instruction manuel. I am wondering what size belt this machine takes? The one on the machine was cracked, and finally broke. I did find an instruction manual for this machine online, and it says it's a "v belt". Doesn't mention anything about the size. The model # is 615074, and it does say made in Japan on the front. Thanks.
