I’ve been offered a revo shaft on a trade deal. The size is not stamped on the shaft however the logo/serial number is on the opposite side. I’ve been told the original 12.9s weren’t stamped until the 12.4s came out? Can anyone verify this?
I bought a revo when they first came out, and it doesn't have the 12.9 stamped on it. I believe this was before the 12.4's came out so you're probably right.
I also had an original REVO shaft 12.9 with L.E. REVO package when first introduced and it was unstamped. Had serial #. The 12.4 came with the stamp when first available.
