Does anyone know the difference between the 29-1, and 29-2. I need the difference backed by some type of liturature. Information about what years were available in what options would be helpful. Here's the generic information I have: The e-29 was available with atleast 2 different rigs - one 'standard' the other IOR(taller mast but shorter boom) PHRF NW - Table III lists different BALLASTS for the two types, but the internet Table III gives no standard measurements for the e-29-2. Anyone have any information that could back up the actual differences between the two designations? Thanks, kjs
