Derailleur specs: "GS"?

A Shimano rear derailleur lists its capacity as:

Total Capacity 42T(GS)

What does "GS" mean?

Thanks.

GS= Long cage
SGS= Really long cage

The idea being that, the longer the cage, the more chain capacity the
derailleur can handle.

SS=short cage
SGS=long cage

The total capacity would be taking the large chain ring up front and
subtracting the smaller ring and adding that to the same math for the rear
cluster. As an example: Compact Crank 50/34 = 16 11/28 wide range
rear cassette = 17 Total capacity needed: 33

Thanks. Now enlightened.

How does one know if it's a GS, SS, or SGS? Is this printed anywhere on the
mech?

Thanks.

have a look for an impression on the face of the inner parallelogram
arm(towards the spokes). If you find it, the whole model code will be
there.

Shimano changers have a part number (RD-something) on the
back side of the body

Correct but SG or SGS is not on it. I just checked my spare LX one. Why
not measure the distance between the pulleys? If it is 100 mm it is SGS.

That's a center-to-center measurement between pulley "axles"?

Someone offered me a M952 SGS (or so he says it is SGS) which he says
measures 87 mm.

Thanks.
