I see you had the exact same ideas about your Steamtank modelling Atchman!
Mine also uses the commander from the old model and features the old Helblaster (though I can see I made some different cuts to make it fit).
I've attached my turret hatches to the side though, otherwise they look shockingly similar (except that mine has absolutely no paint on it yet).
That Helblaster is nice on the Stank but misfires can quickly totall the Stank. A friend borrowed mine once, first turn: fires Helbalster, 1st die, Misfire, followed by a 1 and gone were a bucketload of hullpoints.
Next turn he uses 3 points to try and move forward but blows his boiler.
A complete waste of points there.
Good for you that you managed to get a draw in spite of the loss of the Stank and two of your warmachines though.
Thanks for the nice report, next time remember to keep on taking pictures even when the battle turns against you!
