Handy that it is. I'm researching an old Schwinn I found that has the Seven.

The Suntour derailers (other than 3040 models) and the Shimano friction derailers all had an actuation ratio similar to old Dura-Ace.

If you connect a Seven rear derailer to a Shimano 7- or 8-speed shifter, you can probably get it to index a 6s freewheel pretty well.

Depends quite a bit on details such as the chain used, the sprocket teeth, the B-tension chain gap, and especially the cabling (cable length, whether modern shift housing is used, and if the cable runs only against plastic-lined surfaces).
