These are 2 resin Grav vehicles ( minus their turrets) which I bought from LordNth in 2013 , here they are for comparison.
Excellent models if a bit narrow for 15mm but they would be great for 10mm.
Together with these I got a Highlander ( suitable for 15mm)& a Bushwhacker mechs ( suitable for 10mm) .
If you can find any of his mecha ( I can't find any at the present ) & I don't know whether he still makes them , get them as they are super.
Will build & post eventually.
