If it helps here is my `get by`
Needed to create some rolling stock for the boards, the scale is a bit mixed up but here goes:
Russia is narrow gauge in WW2 so HO/OO track is fine but I needed `O `gauge or `ON 30 `Gauge for the carriages. So I cracked of the bogies of HO/OO to match the track and hand built some quick carriages to reach the scale I needed.
Still have to do a couple of flat cars but under advise for my m8 Ade waiting for the early T34`s before sorting theses out.
The open top carriages are metal and will be a grey colour but the rest are wooden and will be a weathered darkish red.
