Thank you, Si!
Now todays update will cover my way of doing the octuple PomPom's. Essentially, it's a weird mixture out of the original kits parts, WEM Pro set, the Eduard PE and Master barrels (and a tiny piece of plastic card).
Here we go, that's what I used for one gun:

Here's what remains from the WEM pro kit, basically the gun breeches:

A little piece of plastic card attached to account for the different length of the barrels - ok, that part is fake... and eight 0.5 mm holes:

The gun cradle from Eduard

...and with the breeches:

The gun base or platform is from the Trumpi kit, but modified to fit the Eduard base:

Preparation of the Eduard base as an overlay to the kit's part/

The joining of the two:


Some tiny boxes:


Most of the small stuff installed:

The Master barrels installed, all same length but the little fake does its job...


The ammunition boxes, four of them needed for every gun assembly:






The guns without platform completed:


And finally all joined together:

Some copper wire added:





The Repulse's set of three:

Painted in 507 a:

And one installed on the after superstructure:

Quite a lot of work, and to be honest, the first went into the trash - luckily material for four was provided (some Eduard parts I could sneak from a different kit where they would not be needed...), so I hope you like it!
Next update in a few days, thanks for looking in,
cheers,
