The white and blue truck pulled up this morning and a couple of razors that I scored on eBay arrived including a really nice super speed (rocket) that I picked up out of a curiosity to give it a try.The razor only looked so-so until I got at it with the toothbrush and 55 years of crud fell away leaving me with a damn fine looking razor, I loaded her up and took her out for a test ride and I was quite surprised at the blade exposure, My regular date is a '59 fatboy and my guess would be that the equivalent on the adjustable is at least a #7 I also suspect that the angle or geometry is a bit different too on the SS.
