it's the big B & M G11 ( colour lightblue ) signed  " G11/2 " made in the early 90s ( around 1992 if I remember well ) with size around 40 mm.
it was made in two versions :
1) soft ( H = around 25 )
2) hard ( H = around 30 )
of this kind of ball there is also a B&M prototype with the same size ( 40 mm ) but much softer ( around 18 )
S for the 3 balls is around : 32 for the 2 G11/2 and 35-36 for the big K13 Vorlaufer
G is around 50 for the G11/2 and around 44 for the big K13
