Just remembered Wayne (not that it makes much difference to the model), but I have some info about the different warheads used against various types of targets, in Peter Stahl's book, which very basically describes what type was used against, for example, bridges, b-houses etc.
From what I recall, without consulting the text, the 'nose' fuse/probe, and type of charge, was determined by the target 'type' - that is, hollow charge, HE, AP etc.
Just shout if you want more info and I'll dig out what I have.
