Hmmm ... had not thought of this, but its the way to go on a 'B'
... on the 'A' you will need to purchase as set of filters and a set
of stub stacks as the 'A' rear plates are flat ... hmmm ... wonder
if the 'B' backplate could be used in conjunction with the 'A'
frontplate?  In theory, fitting just a set of stub stacks to the 'A'
