I recently bought a copy of Bob Giglio's "Dunsterforce Adventures in 1918", along with a copy of "Setting the East Ablaze". I have been on the fence in regard of the period for some time, but I don't think I can resist any longer... :-)
My immediate challenge is in regard of scale: I already have a fairly significant collection of colonial and WWI miniatures in 15mm, and I would hope to develop this project as incremental to the existing lots, rather than starting from scratch in a different scale. Furthermore, I have limited room for storage and gaming, so I need to be careful. My first step is taking stock of what is available on the market. I am surveying available miniatures in the ranges by Peter Pig, Irregular, Minifigs, Khurasan, Lancashire, QRF. Since my immediate interest seems to be the Caucasus and the 'Stans (the Third Afghan War of 1919 is another subject of interest) , I am particularly interest in all figures wearing headgear that would suit the region and the time.
Before I go too far ahead in reinventing the wheel, though: has anybody else completed such a survey before? If not, I will collect my notes and share on my (long dormant) blog. Suggestions about what to include will be very welcome!
