Oh man, if I did that to all my retired hilts, I'd end up losing multiple grand... and a few years worth of installs.
Idk, I kind of like the ones with old boards, there's something nostalgic about those frozen-in-time hilts. My Iron Man still has a CF V3, and I don't think I'll ever change it.
I still have my K3GR1. It's safely tucked away with two of Jon Judges' brass masterpieces (brassterpieces?) and possibly a brass/copper sibling.
