Are these 3,7 cm Skoda fuzes for the Yugo M1934?

[Hoeksel]

Both look the same to me and in D50/8b I think I recognize these as for the Yugo 3,7 cm Skoda M1934 AT gun, named 3,7 cm Pak 156(j) under German occupation.

Yugo fuze I observed are all marked Гр37, 75, 80 100 etc... without cm or mm
you already posted a HO jugo fuze for 3,7cm

Just 4,7cm Skoda M38 fuze is different
