Hope you get your Mojo back Mike. I really want to see that finished.
Okay, so my OCD side came out with this Matchbox kit. I couldn't resist detailing the M16 a little, as the kit is very basic in some areas. I wanted to use all the kit parts, so I went a little sparingly and detailed, not replaced.
As per previous pic the rear of the gun platform is just a flat wall in the kit, where in reality there no wall, it is open to see the rear of the seat and bracing, etc, plus a gas powered generator and battery are located there.
Then I drilled out the headlights - will fill with clear epoxy later - and made up some stowage from Magic Sculpt and styrene. I also removed the single Jerry can handles and replaced them with a 3 bar one made from stretched sprue.
Then decided to replace the rectangle profile rails with the proper I Beam shape. Dremelled out the rails and where the one piece moulding had the rails between the sleepers, not on them. This now shows the correct open space under the rail between the sleepers. 3m pieces of strip styrene used here to form the rails, not I beam styrene. That enabled me to a bit more drama to how the damage is depicted.
Need to add some brackets to retain the rails and some other improvements here.
