Answer from "Old Willys " Forum
"Wicker" wagons were 'upscale' trim packages - ah, marketing!
'48-'50 "Station Sedan" (all 2wd) had 6 cyl, OD, stainless grill trim, deluxe upholstery, one piece rear seat, spare mounted on floor, 'Jeep' Station Sedan on glove box & hood... had basketweave adhesive decal in top panel below glass.
'53 "Utility Wagon"- same basketweave insert in top panels marketed as "Deluxe"
Willys America sells sticky repros, and there was a beautiful '53 Deluxe featured on January cover of 2009 Classic Jeeps calendar
Station Sedans (and my '49 663 - maybe all early models?) had herringbone cloth headliner
Hope that helps
