Neat job Papa... and great detailing writeup on the wheels, which is what usually snookers most model builders... especially a satisfactory indexing methodology...  Ya gotta get yourself a cuttable laser or CNC for those jigs... other than my puzzles, about 90% of my laser use is for templates and jigs... thoughneat but laborious scrolling work... though hard to get right as oopsies are hard to hide.... BTDT.

I've never been a fan of painting these type of models, however, you have captured the esthetics of the WW2 jeep perfect.
I actually have the plans but never got around to making it up  (bulk bought a swag years ago when they had a sale and it minimised shipping.
FAIW, I have imported it into SU and is available at the 3DW,
(bit late for you though).
I have uploaded a swag of their models (and Gattos) that I have imported... naturally the plans are not included, but it they give a better 3D perspective.

If your first cut is too short... Take the second cut from the longer end... LBD
