Here are the parts laid out for the Ammo box,as usual trim from the sheets and remove the nibs with a swiss file.
Assemble the box with your favourite white glue,allow to dry and sand smooth.
Cover the box with lightweight model aeroplane tissue and apply three coats of thinned PVA adhesive between sanding down.
Paint the Ammo box RLM Grey which is a good match.
Attach the mazak fittings after trimming with a swiss file,I used medium cyno,make sure they are level.
A dry run shows an alignment fault to accept the guns,you will need to adjust the ammo box holes and also take a slither of wood from inside the edges of the box in order to align the guns,do not fix them in position yet.
I am working on the ammo cartridge ejector guides,currently experimenting with the best way to make them up,probably litho plate.
