Never could source any original bomb carriers for the 4.2" rounds so ended up fabricating my own. The T-16s that were used in the mortar platoons could have 48 bombs in bins over the tracks but the variations I'm building will only have them over one track behind the gunner. Have a single 2" and 4.2" round laid out for size reference.
Shot shows the bomb bins with twelve carriers installed (24 rounds) while doing the test fitting. Still need to build the divider panel from the engine compartment at the rear which allows for carriage of twelve PIAT rounds in four smaller carriers.
This picture shows the angle iron rail that was used in place of the side skirts. Allowed easy access to the tracks without having to be removed and provided a continuous place to stand so bombs could be quickly and easily loaded and unloaded.
And this last shot shows the bins from the rear along with the wood trim along the edge of the armor which is finally installed.
