Ah, OK that works with my example script - thanks.  However, that means 
the Bitstruct definition I gave is incorrect.  The binary file I'm 
trying to modify correctly unpacks the integer using :

f.read(3).unpack('H6').first.to_i(16)

However, I'm really confused over what the Bitstruct definition should 
be to support this - do you have any suggestions ?

Thanks
