I understood shamrock asked about the differences between the C38 and F38. I assumed so, because we do not even have a "F28"... so I figured we probably meant the F38 (typo)
So I ventured to explain the differences, which are mainly materials. Why do you see no link between these two posts
Hope it was helpful anyways shamrock, if not, please rephrase your question so I understand it more clearly, sorry!
