Thanks for the thoughts chaps. I have ordered some of the Pulp and Copplestone sailors to try converting. If that fails I'll look at the other alternatives more. Also I have a few more Cossacks, infantry and artillery on the way from Northstar. I have a heavy gun for the Reds that can use the spare gun crew figures and my sadly small, but lovely, order from Studio Siberia has arrived. Just a few character figures for now but I'll want more later. Especially if I do some winter themed units.
Those Warlord Bolt Action Soviet Naval Infantry are nice. Too many SMGs but the MG could be converted to a Lewis and the riflemen have the bullet bandoliers so iconic of the revolution. I'll get some of those to add to my Red Sailors. Some of the Warlord and Crusader Partisans could be useful later too.
I've now made the guns for the Steamer.
