So glad to hear this artillery piece will be in soft plastic. With a 1-piece barrel and a carriage small enough and intended to be pulled by bulls not much longer than a limber with animals, thank you!
The larger WWI Siege Cannons can maybe benefit from hard plastic with 2-piece barrels and so many tiny, detailed add-ons that must have glue.
I will always prefer soft plastic for all except for some forts (Airfix Fort Sahara) and all tanks.
Remember, Atlanic had a whole range of Ancient War Ships and Artillery. They pressed together fine, and didn't droop if you kept them off of hot window sills.
