Stummel shell size

I recently purchased the 1/35 Eureka shells for the 39 Kw.K37 for my Tamiya 251/9. These things look so small!! It looks like a man could easily pick one up with one hand and load it. Is this right or did Eureka make them too small?

Yes, they were small. The Stummel used only a 75mm low-velocity gun. 75mm is just under 3" diameter for the shells and being low-velocity, they had short casings.

The various shells used with the 7,5-cm KwK 37 weighted from 4,4 kg to 6,8 kg ( https://fr.wikipedia.org/wiki/7,5-cm_KwK_37 ) …
