there is only one version of a bp sub c insert.but there is variation between them ,the insert that came on my bp sub c has a thinner font than the other 3 inserts i have.and one of the other insert had thinner font,also they are all different thickness ,one of my fits beautiful and flush all around the bezel,but the others the top part with the triangle is thinner than the end with the 30 number,so the to sits too low in the bezel and looks [censored].so its hit and miss to get a perfect insert that fits great and has perfect thick engravings.
