Well, as I always seem to do, I made it to big :-/ I don't think he'll mind though :-).
It's rather similar in layout to my 28mm blockhouse (picture below) but without the small ancillary building. Simple earth bank and stone base to the blockhouse itself.
Here you can also see the first floor of the blockhouse. this was made from 3/4mm square balsa strip. It's been 'distressed' a bit but not too much as the grain was quite predominant already.
You can see here the gate also. I left off the doors because at this scale they would be prone to damage (here's hoping that the gateway itself lasts...).
The next thing I did was to sand over the whole base but I don't have a piccy of that (I think you know what I mean ;-).
And below are a few shots of the finished thing with a shot of the 28mm version for comparison.
The next bit of AWI terrain today is a simple artillery redoubt that could probably be used for a number of conflicts (ECW, AWI, ACW etc).
Simple foam shapes for the banking covered with cheap wall filler and some balsa scraps for the gun deck.
The whole thing was sanded and given a wash with thinned brown ink. once dry the whole base was drybrushed with various shades of beige and tan.
On there is my only (for the moment) AWI cannon, British of course but I've got five more of these and about three American ones. I've also got limbers for them as well and one is nearly done :-)
Another shot below and hopefully you can see the flock appearance.
