marked changes in appearance. The
few Rileys in Manchester have a
superficial similarity to the BISFs
built adjacently, with similar
cladding to the first floor elevations.
Telfords were relatively few in
number. They are characterised by a
protruding band course at first floor
level (Figure 3.51).
