So I was going to swap a monitor into my Rampage when I noticed the labeling and writing on the tube (see pics). Color XY? So I googled the Atari part number on the tag and it comes up amplifone? So I check my extra Amp tube and it has the same part number. Is it possible that the tube was repurposed to raster? The frame looks like it has transistor holes similar to a K6100. Definitely an odd one.

Could be. The tube # was on the missing larger decal under that Atari sticker.
The Amplifone XY monitor used a M48AAW00X tube.

Maybe someone else will recognize other stickers/markings to be able to give a confirmation.

I have read that the M48AAW00x had a finer dot pitch then an A48* tube would have, though I've never confirmed this via spec sheets. Beyond any difference there, there is no real difference between a raster and vector tube except the yoke. Just match up 90/100 degree, and make sure the pinout and grid voltages match up, and for the most part they will interchange.

Not too surprising that an operator would have re-used the tube if possible. No doubt the HV failed, they raided an old pulled game for a WG 6100, dropped it in where the Amplifone had been getting (likely Star Wars) the game back up and running, then as a plus, reused the tube in a game that had a tube die.
 
I believe,

19VLUP22 was only used on K6100 and G08.
M48AAW00X was used on the 19" AMP and high-res rasters (K49xx and K7xxxx).
A63AAX00X was in the 25" AMP.

Right again. The 19VLUP22 is a 100° tube used on the 6100 and G08.
The M48 tube is the finer dot pitch used on most Amps, but some also used the coarser 19VJTP22 tube. Both are 90° tubes and need a 90° yoke.
The A63 tube is a 100° tube which is why the same yoke as the 6100 was used on it. It does not matter that the tube is bigger since the angle is the same.

Well, A tubes don't have a dot pitch as the phosphors are arranged in continuous vertical stripes so it's a stripe pitch. The phosphors on M tubes on the other hand have a dot pattern so it should be easy to tell if it's an M or A tube by just looking at the screen.
