Does anyone have the ERD for 1970s Mavic SSC rims? I have found one listing that puts this at 616.0, but I would like a bit of back up on this, if anyone has a listing.

Also, circa early-to-mid '70s, is it safe to say that a 4X lacing pattern was used more often than 3X, regardless of low-flange or high-flange hubs? And 15/17/15 spokes were used in most instances during this time period, were they not?
