I've carried my mammoth scaled Vic Executive most days to work since I bought it (2012?) Today, I noticed that one scale was separated a bit more than usual. So, I ran a fingernail under it. Lo and behold, it was delaminating from the tool!
Slipping a thin knife blade in there and working GENTLY, the scale popped right off!
This is a shot of the scale right after I bought it, (basically right out of the box):
I'm going to sand down the scale and see if I can get it flatter, then re-attach it. Basically, it looks like a standard epoxy glue.
BTW, the scratches weren't of my doing. I'm guessing they had a time getting this scale on originally.
