A while back I bought some "transitional" winged tuners with square-backs that they used for the old Artist series of guitars. One of the tuners was messed up and slips so I put 'em off to the side until I could get a replacement..
So that isn't happening. What I got instead were two spare Schaller wings that I'm hoping to dismantle and swap worm-gears on, if I can.
Otherwise I may just have to go unmatched and use one of these Schallers instead.
I tell ya, it's getting harder to find wings in the wild. I have two guitars left (stop tails) without them and when I finish these (for the Gucci Top) all my spare parts will be (mostly) used up.
I'm getting to the point where I won't even be able to look at buying another PRS unless they come with wings already.. Call me a "flat-earther" or a caveman, whatever. I'm Just Maintain' in 1987 over here.
The wingies were such a clever, unique, locking tuner design - I kind of miss the classic look they gave PRS guitars.
I do think the new lockers are easier for novices to use (and I always managed a little too much slippage on the high E and B strings), but the wingies had a cool thing going for them.
