Not the result I expected for the sketch but oh well. Time is up!

 

After My almost finished Sten MK II was almost done suddenly my Max Crashed while I was saving, so I remade these parts again from scratch for 4 hours and because I was working while I was angry I made so much mistakes that made me very slow in doing this. so yeah the rest will be done hopefully soon....

References are as below I made the exact sizes so I got the proportion right...

I am using 1 unit for every diameter  those small lines are actually 1 unit based on the smallest diameter of the gun

Painted by Photoshops using references bunch of Hands and collage them together
