As already noted, there are almost as many codes as makers. In my (very) old
Centerlab Catalog, I did find references to W-Taper pots, but nothing conclusive
at all on K or k taper as a specific reference.

With the additional hint of this being a slider, further googling got me to drill bits,
but nothing on pots, linear or rotary.

That's exactly what I found on the web. In other words, NOTHING
regarding the K-taper. But I did find the W-taper and it was explained
the same as you said. I found some forum where they were discussing pot
tapers and some mentioned even more letters, such as N, S, M, D, and a
few more. But not K. And yea, I managed to bring up drill bits too.

This pot is R60, (master volume control). It's a unusual type of pot in
the sense it's mounted to the PCB and mounted backwards, meaning there
is a small piece of metal (ring) attached to it's rear, that is soldered
to the PCB and the three tabs are bent downward, where they are soldered
to the PCB.

I have not yet taken it off the board. The pot does work, but the shaft
is broken below the front panel surface. My first thought is to contact
Altec Lansing and see if I can get an exact replacement. If not, I may
try to saw off the remaining plastic shaft so it's flat, and make up a
"sleeve" for it, (a piece of metal tubing) and glue another shaft to it
with the tubing to reinforce it. This shaft should be about 1.5 inch
long, (before being broken) so I have room to work, since there is
still a half inch to work with. If none of that works, I'll have to
Mcgyver some other pot in there, and will choose an audio taper type.

With any luck, Altec will have a replacment part. That would be the
easiest fix.

A while back, I found out that Peavey electronics does have parts for
all their old stuff. I hope Altec Lansing does too.

For reference, there is a lot of useful info about pots on this website.
