Still working on it.

A few sections have been finished and initially sprayed grey. The colour looks reasonable so it will probably be kept.

However, the brick/stone work is taking an age!

I'm using a biro for running with the grain but this monster for the cross grain cuts. It's heavy and awkward but anything lighter tends to skip.

The problem with balsa is that sometimes it shreds or flakes when you cut it - difficult to sand and the ends refuse to go smooth. Hence some of the parts need copious use of liquid green stuff to give a workable surface!
