drive mounting plate

I have here what appears to be a drive mounting plate, of the sort that what my admittedly fuzzy memory is telling me was used in the Wang PC (not yer typical clone). It's a fairly heavy bit of metal, seems to have holes in it suitable for mounting a 5.25" drive, one folded-down lip to mount it to the box with, and a bit of a tab sticking out the other side, which was probably for orientation (I haven't seen one of those for probably 20 years or more). Anybody have a use for this? If not, it goes into the scrap metal box... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.
