I will go through some of my spare gen inserts tonight to see if i can find any dimples and report back here thereafter.

Now that i have looked through several, i realise that the older ones tend to have the ridge dimples. Although i see some without. So though its not conclusive, i would agree that ridge dimples is part of the manufacturing process for older inserts. The ridges are also far wider than the newer ones with thinner ridges.
Those with thinner ridges hv no dimples.
