Narrabri 3 bay Engine Shed built from a photo on the front cover of BYWAYS of STEAM No 28.
The kit has a footprint of 212mm wide x 372mm long and stands 142mm high. As you can see from the photo it can fit just about anything in HO scale.
The laser has done a great job on the roof ventilators. Just paint the parts any colour scheme you like and glue together.
We don’t claim it to be proto typical.
