Rob, Your manual is the sixth revision. The part number for the origal SB-401 manual is 595-947 and those after that would be -01 -02 etc. If the manual came with your SB-401 then you should see the 06 in the series number on the blue and white sticker. I don't remember which digit is what on the stickers but I do remember that the center or third digit is the year that the kit was made. So a center digit of 5 would indicate the kit was made in 75, 85, 95 etc. Too bad they didnt use a two digits for this purpose.
