The set includes turned brass barrels for Hispano MkII Cannons.
It is very simple to use in Your model, and makes it extremely realistic. Simply cut off the original plastic barrel and drill a hole in the remaining plastic parts and insert the metal barrel using Cyanoacrylate adhesives. The hole for the inner cannon needs to be 4.1 mm and for the outer cannons it’s 4.4 mm. The outer cannons have longer fairings, so be careful you get the right ones in the right places.
If you want Hispano Mk I cannons with flat recoils springs then you need to look for set Am-32-074.
A highly recommended and simple update to your 1/32 Hurricane build.
Many thanks to Master Modeler for the review sample.
