Station building for the O gauge

I know I said I'd get this done in two days, but I keep fiddling. Curtains were one - simple magazine paper - but with internal walls fitted was a bit of a fiddle. The already mentioned fire buckets needed a) painting (more on that later) b) a back board made up from some Ratio building sheet mounted back to front with curved hooks made up from staples.
I went a bit full on with the weathering. This is probably wrong as most wiggly tin buildings on railway property are quite well maintained, but the temptation to add some oxidisation is too strong.

All that's left to do is add finials to the bargeboards and a stove pipe chimney round the back, both left to the end of the build as I knew the handling would knock them off. Plus a minimal amount of signage to set it off.

Quite a bit of this leans on Gordon Gravett's piece in MRJ 245. I only wish etc.
