I was taken with a picture of a small mullet cannery in a New Zealand harbour, dated about 1930. A couple of sheds and a small jetty for sailing mullet boats to tie up and unload. Suitable for N scale railway.  The buildings are printed separate from the piers for two reasons - to aid in painting and to allow a change in building design. There may be a small gap along the roof ridge, fill it with plastic putty.
