I have a late serial number International H4 magneto (S/N H41477132)that has a different style impulse coupling from the common coupling that has the rectangular drive lugs. The coupling on this mag has a rounded over drive cup and the drive lugs are round pins about 3/8" in dia with flats on two sides. The coupling has an R stamped on the outside of the drive. The drive pins seem to engage the standard mag drive without any problem. I would like to know if this coupling is a standard 35 deg advance that would work on my '47 Farmall H. The mount base on this mag is also made of cast aluminum instead of cast iron. I don't have a picture of the impulse coupling but I just noticed one like it listed on ebay (item # 350412285043) if anyone would like to see the type coupling I am questioning. Any advice on the type and advance on this coupling would be greatly appreciated. Thanks.
