I was inspired by your mod to create a model of the AS "Squid" projectile, in case you find a way to limit the number of charges dropped by the thrower to three.
The 576-vertices 1100-polygons model is based on the drawing posted by Anvar, and it measures ca. 305 cm (12 in) in diameter and ca. 150 cm in legth.
Paint colour, markings and other details featured by the model were taken from the drawing mentioned above and from some photographs I found on the web. Nonetheless, most of those pictures portrayed later versions of the squid bomb. It is possible that under some respect the model is not a fully accurate representation of the WWII marks, but it should get close anyway.
Let me know if you would like me to send the model your way
Next, I plan to model the squid thrower. It will take a bit longer though, mostly because I couldn't find any technical drawing of the real thing, and I will be forced to infer some features and general proportions from photographs.
