Good stuff Vic. The RPs would depend on the target type, and there were three types - the 60lb HE head (that's the bulbous one), 25lb SAP HE, which was not as bulbous, and the 'slim' one, the AP round, which looked similar to the American HVAR, but was a smaller diameter. The latter were normally use on anti-shipping ops, sometimes with a mix of these and 60lb HE or 25lb SAP HE.
From what I remember, the kit provides the AP rounds, and if you need them, I have some good close up photos showing the RPs, the mounting saddles and rails, and the 'pig tail' ignition leads.
