hiya kevin the difference in the scale is minimal
when you try these on a models i have modelled in both scales and they both
look good on various models i agree different manufacturers seem to make
them a bit larger than the scale they quote but different moulds i suppose
well let me know if you disagree but if you want 1/35 scale try military miniatures
u s gun+mortar team set from tamiya you could modify these hope this helps
