Various design prototypes is just good practice. Even if the first prototype turns out to be the best, you can only know that by making changes. If the first prototype goes to production without ever having anything else trialed, it is a sign of lazy design and a cheap product.
A version, is generally considered a finished product that is released for sale. Generally (unless done for marketing purposes) a change in whole number is reserved for significant changes, changes after the decimal denote minor changes.
looks like the comb is a little lower!
