This kit was a dream to put together, which agrees with everything I've ever heard about Rubicon. Even better you get an extra hull and turret so you can build a regular 75mm and swap them if needed (its built so you don't have to glue the hull and chassis!)
The trickiest part was painting the camo on the barrel. Panzer crews quickly raised how deadly the 17 pdr was and would target the firefly in each tank troop first, so the crew camo'd the end of the barrel with a disruption pattern to make it look like the 75mm.
I'm looking forward to trying this bad boy out, i'm sure it'll suffer from the newly painted curse and explode in the first couple of turns.
