The 100 you see is probably the ammo loadout for AP rounds. In SPWW2 penetration is in cm, not mm like SPWaW.

To see the PEN of a weapon, click on the 'unit data' button when in the purchasing screen, or the 'Information' button when in a battle, after right clicking the unit.

The 3.7cm Kwk 35 L47 has:

PEN 5 (1 with HE rounds)

If you want to see more info about a guns penetrative ability, there's a file called:

WW2_APCalc.exe

in your main WinSPWW2 folder.

Execute it, load the nation, then the weapon.

The 3.7cm Kwk 35 L47 with AP round will average 5cm penetration out to about 200m, but may get as much as 6cm.
Averages 4cm out to 450m and 3cm out to 600m.
But may get as much as 4cm out to 1200m, if you're lucky.
