Since the angle matches up, I think it looks safe still (unless the bottom has more reinforcements that I don't know about and are lacking here). I'm not sure why one would do this mod and not just go with a smaller/lighter stem. At least I think it's a mod. It turns out it wasn't the minimum insertion line that I saw (really faded), but the notation saying "For 26.0" that's right at the bottom of the angle and almost cut off. Was there a shorter version of the technomic that I'm not aware of?
