Btw, the in game G7a torp seem to be textured light gray and with blue'ish warhead.
Here is my first attempt:

I should try to make it 1px higher and with better contrast.
Odd, the same T1 torp image seem to scale differently.
Lol typing text was a bad idea. 'T1' is mirrored for rear tube.
I suppose you can make two versions, it's the same with me. I'll likely work on this further. Some might find the torps too slim perhaps.
Calculations show that the small torp is about 1-2px too long. Easy to adjust.
Here is the larger file:
